This sugar-free raspberry jam is perfect. It’s thick and jammy and has just the right level of sweetener. Added bonus, it is completely shelf stable up to a year!
Got a bounty of raspberries? Make your own raspberry jam and raspberry filling for all your low carb baking. I made this raspberry jam specifically for these coconut raspberry slices, but you could use it for so much more.
This jam is naturally gluten-free, low carb, and keto-friendly.
There is no added sugar in this recipe, only the natural sugar from the fruit.
Why canning up extra jam is always a good idea
Versatility.
People think jam goes on bread. Sure sure, yeah of course it does, but it does so much more. It is such a great pantry item to have to whip up all kinds of desserts or to add a punch of raspberry flavor to just about anything.
Think of it as a raspberry filling.
Perfect for the top of a cheesecake, or filling for a cake, add it too tart shells, or make some low carb thumbprint cookies.
Like I said, versatile.
Making your jam also allows you to control the ingredientsandlevel of sweetener in your jams. No weird ingredients, no weird taste, just natural fruit-flavored jams.
PLUS making your own shelf-stable raspberry jam is a great way to save some cash. Have you seen the price of a small jar of sugar-free jam?
Not all pectins are loaded with sugar.
Ok, so now let us talk about the pectin issue.
Pectin gets a bad wrap in the low carb world. You will often see recipes say “made without pectin”, and that’s because even the low sugar pectins have sugar in them.
Ok, so what’s the solution?
Real pectin is the solution.
I found this great product called Pomonas 100% pure pectin. This isn’t a sponsored post. I legitimately adore this product.
No sugar required, but you do need to use a sweetener. Stevia, xylitol, erythritol, monk fruit, allulose – it doesn’t matter, it will work. I tested ALL of them to see what sugar replacement would work best and they all worked exceptionally well.
And carb counts? I quickly found the full nutritional information on Pomona’s website:
One teaspoon (3 grams) of Pomona’s Universal Pectin contains:
10.2 Total Calories
2.55 grams carbohydrate (from soluble fiber)
2.5 grams of soluble fiber
Since we’re only adding 2 teaspoons to the entire recipe (over 64 servings ), the carb additions are negligible.
Pomona’s pectin is vegan, gluten-free and non-GMO.
PomoNa’s 100% pectin
So if you have canned jam before this process has a quick extra step.
There are two types of pectins – pectins that require sugar to gel, and pectins that require calcium to gel. There is a whole scientific explanation on Pomona’s website if you’re interested. The package of pectin also comes with a small package of calcium powder, no need to buy anything else.
The calcium powder gets mixed into a small jar of water (which lasts forever refrigerated). The calcium water is what gets added to your jam recipes, usually a teaspoon or two at a time.
SO easy.
You can find Pomona’s pectin on Amazon, or in health food stores. I paid a little over $8.00 Canadian for a box. I balked at the price but did not realize that one box will make up to 22 half-pints (8 ounce) jars.
Working with PomoNa’s 100% pectin
I found working with this pectin much easier vs working with regular pectin. It seemed much more forgiving. If the jam didn’t gel to my requirements I could add more calcium water and it would thicken.
If I added my pectin and sweetener, I could always add more sweetener and continue to process without over thickening the jam. This was great because I wanted to make sure my jam was sweet enough, but I didn’t want to over sweeten at the start.
Additionally, If you have jars of jam that don’t quite set after they are cooled, you can reprocess them and add either more pectin or more calcium water to get the gel to thicken.
The instructions come in the box, and they are super easy to follow. Pomona’s also has a fantastic website with all kinds of instructions and base recipes for you to work with including instructions for developing your own recipes.
- Quick note: Use filtered water in your recipes. If you have hard water (which tends to lean heavy on the calcium already) they will thicken more than you want them to – so just be mindful that your water can play a part in how thick your jam gels.
What are the best sweeteners for this low carb raspberry jam recipe?
I tested them all! My kitchen will be forever sticky after making a billion bottles of jam. (I hyperbolize it was only a million)
I tested Stevia (which I am not a fan of in the first place, but for testing, I gave it whirl), Swerve, xylitol, erythritol, monk fruit/ erythritol blend, allulose, and Truvia. They all worked beautifully, but some stood out above the rest.
Check out Pomona’s website for details about working with stevia.
By far the sugar-free raspberry jam made with Allulose was the best. It had a sticky gooey texture that commercially bottled jams are known for, and had the best taste. It straight up tasted like jam. By far my favorite.
Erythritol did have a tendency to turn grainy when cold, as erythritol tends to do. If you warmed the jam up, it was perfect. So if you want to use Erythroil just know that graining up when cold will happen.
I also tested my favorite sweetener, So Nourished monk fruit erythritol blend, and it did grain up a tiny bit but not as much as straight-up erythritol in the recipe.
Xylitol was GREAT, but it does add additional carbs, so not my favorite for that reason.
Truvia, Stevia, and Swerve worked fine, but I find they have an aftertaste for me, but that’s personal. If you like Truvia, or stevia, or Swerve, absolutely use them. The jam gelled beautifully, and the fruit held the colour and texture.
****If you use Xylitol, remember that it is poisonous to dogs and cats! ****
If you don’t read anything else, please read these important canning tips.
There are a few safety precautions!
This sugar-free strawberry jam requires a full 10-minute rolling boil to seal the jam jars – DO NOT skip this!
- DO NOT skip the lemon juice. Use bottled lemon juice. Fresh lemons vary in acidity, and you want to make sure you get your acidity level correct. Using bottled lemon juice will ensure you’re adding the right amount.
- Do not use a jam bottle larger that 500ML(2 cups).
- When you pull your sugar-free raspberry jam bottles from the canning bath, leave them rest for 24 hours without moving them, or tilting them. Let them set.
- Any jars that did not pop or did not seal properly can be reprocessed in the water bath for another 10 minutes, or stored in the refrigerator for up to 3 weeks.
Storage & uses for your low carb raspberry jam
Store these jars of ruby deliciousness in a cold dark place for up to a year. After the sugar-free raspberry jam jars are opened they can be stored in the fridge for up to 3 weeks.

Sugar-Free Raspberry Jam - Shelf Stable, Low Carb and Delicious!
Yield: 4 Jars ( 8 ounces jars)
Prep Time: 15 minutes
Cook Time: 17 minutes
Additional Time: 1 day
Total Time: 1 day 32 minutes
A tart but sweet raspberry jam made without sugar. This jam is shelf-stable for up to a year and you can make it with your favorite low carb sweetener.
Ingredients
- 4 cups mashed raspberries (about 8 cups whole raspberries)
- 2 tsp calcium water
- 2 tsp Pomona’s pectin powder
- 1 tsp vanilla
- 2 Tbsp lemon juice
- 3/4 cup allulose
Instructions
- Wash jars, bands, and lids. Place jam jars in water bath canner filled halfway with water. Bring water to a boil. Turn off the burner and leave jars in canner until ready to use
- Place lids in water in a small saucepan and heat until water simmers. Keep lids in warm water until ready to use.
- If using fresh raspberries, clean & remove debris before adding to a large saucepan. If using frozen measure and just pour right in.
- Add lemon juice and calcium water and blend in well.
- In a bowl add allulose and pectin and blend well.
- Heat the raspberries and as they start to soften, mash with the back of a fork, or use a potato masher. I like to leave a few whole berries in my jam, but mash to the consistency that you like. Bring berries to a boil.
- Add pectin-sweetener mixture, continuing to mix for 1 to 2 minutes to dissolve the pectin while the jam comes back up to a boil. Boil for 1 full minute once the jam reaches the boiling stage.
- Fill jam jars to ¼” from the top. Clean rims with a clean cloth. Add lids.
- Add jars to the water bath canner when the water in the canner reaches a full boil. Boil 10 full minutes (add 1 minute more for every 1,000 ft. above sea level).
- Remove from water. Let jars cool undisturbed for 24 hours.
- Test for seal, if a jar did not seal, you can reprocess it again in the canner for 10 full minutes, or add that jar to the refrigerator for up to 3 weeks.

FAQs
Is low sugar jam shelf stable? ›
Once opened, low sugar jam doesn't last as long in the fridge either. When you open jars of full sugar jam, they keep for several weeks. But I've noticed that low sugar/no sugar jams start molding and spoiling much more quickly.
Can you have preserves on keto? ›Maltodextrin is not considered keto-friendly since comes from high-carb sources like potato, rice, tapioca and corn. That said, Polaner Strawberry Preserves is still low in carbs at only 2 net carbs per tablespoon. It's a tasty option for those on a low-carb or non-strict keto diet.
Do you need sugar to preserve jam? ›Jams and jellies can be made without added sugar but will resemble more of a fruited gelatin desert than a true jam or jelly. Salt is not necessary for safe processing of canned or frozen fruits and vegetables. It is necessary for the preservation of most pickles and cured or smoked foods.
Can you use less sugar in preserves? ›The answer is that you can always safely reduce the amount of sugar in a recipe, because sugar doesn't make things safe. The only thing that makes a jam, jelly or other sweet preserve safe for canning in a boiling water bath canner is the acid content, because that's what prevents any potential botulism growth.
What happens if you add less sugar to jam? ›"They tell you not to alter because it's the ratio of fruit, acid, sugar and pectin that forms the jell," says Robin Danto, MSU Extension educator for Oakland County. If you don't have the right amount of sugar, you run the risk of the jam or jelly being runny.
What is the difference between pectin and low sugar pectin? ›The classic pectin requires a high amount of sugar in order to set. The low/no sugar pectin will set without any added sugar due to the addition of dextrose in the product. The instant pectin would likely be for freezer jam/jelly and would break down with heat process canning.
What jams can you eat on keto? ›- Strawberry (3.5g net carbs per tbsp*)
- Raspberry (3.5g net carbs per tbsp*)
- Mountain Berry (3.5g net carbs per tbsp*)
- Apricot (3.75g net carbs per tbsp*)
- Blueberry (4.5g net carbs per tbsp*)
- Peach (3.5g net carbs per tbsp*)
Smucker's Sugar Free Strawberry Preserves is not keto-friendly because it is a high-carb processed food that contains unhealthy ingredients like sucralose, red #40, and dextrose.
Does sugar-free jam have carbs? ›Yes, sugar-free jelly will always have some carbs from the fruit, and sometimes from pectin if that is used.
What can I use instead of sugar in jam? ›- 1 – Unprocessed Cane Sugar.
- 2 – Maple Syrup.
- 3 – Honey.
- 4 – Agave Nectar.
- 5 – Stevia.
How can I thicken jam without sugar or pectin? ›
1. Add chia seeds to the recipe. Chia seed jam is a method of making jam that requires no cooking. The chia seeds soak up the juice and moisture from fruit purée and plump up, giving a thickening effect to the jam without using heat or added sugar or pectin.
What can I use instead of preserving sugar? ›If you can't find preserving sugar then just use regular granulated sugar and skim any white froth off the surface of the marmalade once it has boiled and reached setting point and has been taken off the heat.
Can I use Stevia instead of sugar in jam? ›Stevia can only be used in jams and jellies when used with no-sugar needed pectin—low methoxyl pectin.
How important is sugar in jam? ›The sugar helps the chopped fruit retain its shape and texture. Gel: Sugar is one of the three necessary components for jam set, or gel. Sugar molecules grab onto water molecules as the mixture is heated. This allows the pectin to form a gel.
How long does sugarless jam last? ›Once opened, keep your homemade jam in the refrigerator for up to three months. Homemade jams made without sugar and processed by canning in a hot water bath will last about half that long – about one year – when stored in cool, dry place out of direct sunlight.
Does pectin work without sugar? ›No Sugar Needed Pectin is a unique product that allows you to choose both the type and level of added sweetener. Unlike other pectins, fruit spreads made with this pectin do not require substantial quantities of sugar to gel. You can use no sugar at all, regular sugar, a sweetener or honey.
Does lemon juice help jelly set? ›The lemon juice lowers the pH of the jam mixture, which also neutralizes those negative charges on the strands of pectin, so they can now assemble into a network that will “set” your jam.
Can I use regular pectin instead of low sugar pectin? ›Another method is using regular pectin with special recipes. Some tested recipes are formulated so that the gel forms with regular pectin without needing to add the usual amount of sugar. Keep in mind that there is some sugar in the regular pectin. These recipes often use sugar substitutes for additional sweetening.
Which is better liquid or powder pectin? ›Both forms give good results but the methods of adding ingredients differ. Liquid pectin is added to the cooked fruit and sugar mixture immediately after it is removed from the heat. Powdered pectin is added to the unheated crushed fruit. Liquid and powder pectin cannot be interchanged in a recipe.
What can I substitute for low sugar pectin? ›If you want an easy one-for-one substitute for low-sugar Sure-Jell, low-sugar Ball RealFruit is the one to pick. Sure-Jell and Ball can be used interchangeably, but Pomona's is tricky to substitute.
What can I use instead of pectin for jam? ›
Cornstarch. Cornstarch is a natural thickener that works as a seamless substitute for pectin.
Can I have sugar-free jam on keto? ›Yes, sugar-free jam is keto friendly. Blueberries, raspberries, blackberries and strawberries have much less sugar than other fruits, making them great for low carb and keto diets in moderation. Think garnish instead of a whole bowl. Use sugar-free jam just like regular jam – in moderation.
What's better jam or preserves? ›If you prefer a smooth consistency, go for jelly. If you're more into a thick strawberry spread on your PB&J, buy a jam. And if you're looking for a more chunky mouthfeel, opt for preserves or an orange marmalade.
Is sugar free jelly good for diabetics? ›Jams, jellies and preserves made with so much sugar are often not a preferred choice if you have diabetes or you just want a low- or no-sugar choice. The good news is that there are special pectins and recipes designed to make jellied products with little or no added sugar.
How many carbs are in Smucker's Sugar Free jam? ›Smucker's Red Raspberry Preserves Sugar Free (1 real tbsp) contains 5g total carbs, 2g net carbs, 0g fat, 0g protein, and 10 calories.

Is Smucker's Simply Fruit OK for diabetics? ›Simply Fruits spreads are great!
As a diabetic, I love Simply Fruit spreads with no sugar added.
The ketogenic diet typically reduces total carbohydrate intake to less than 50 grams a day—less than the amount found in a medium plain bagel—and can be as low as 20 grams a day.

How many carbs are in sugar free strawberry jam? ›Sugar Free Strawberry Jam (1 tbsp) contains 5g total carbs, 3g net carbs, 0g fat, 0g protein, and 10 calories.
Is peanut butter OK for keto diet? ›Peanut butter can definitely be part of a keto diet, but it's best to stick to plain options that are free of extra flavors and sweeteners. Almond butter is a good choice, too, and it's slightly lower in carbs. Additionally, you should be mindful of your portion size if you're trying to lose weight.
Is jam healthy for weight loss? ›
Fruit jam is highly nutritious and can be consumed as a breakfast item spread on the bread. However, remember that the disadvantage is that they are high in calories. People who want to lose weight or have diabetes, they should use it sparingly since it has high sugar content.
Is homemade jam healthier than store bought? ›Making a homemade version of your favorite jam or jelly is easy, and it'll likely be a healthier alternative to store-bought products.
What is a healthy alternative to jelly? ›Instead of smearing jelly and jam on your toast or English muffin, consider substituting peanut butter, almond butter, sunflower seed butter or a similar nut or seed savory spread. The butters are high in protein, while the roasting process used in making them brings out the natural sweetness in nuts and seeds.
Can I use honey instead of sugar in jam? ›Jams and Jellies with Honey
Ontario honey may be substituted for sugar in most jam and jelly recipes. If a recipe calls for 4 cups sugar, use 2 cups honey. Cook the jam or jelly slightly longer than time stated in recipe using sugar. When substituting honey, use a commercial liquid or powdered pectin.
It will last several weeks in the fridge, but can be frozen for up to three months. Obviously you can use the jam anywhere you like jam — on toast, in peanut butter and jelly sandwiches, or on fresh biscuits.
Do you need to add lemon juice when making jam? ›To set, jam needs the right balance of acid and pectin. High-acid fruits include citrus, cherries, green apples, pineapple, raspberries and plums. If you're using low-acid fruits, such as rhubarb, apricots, peaches and strawberries, you need to add lemon juice.
Can you use maple syrup instead of sugar in jam? ›And I loved it! I think I've discovered that using a mild sweetener like maple syrup still lets the berry flavor be the star of the show and that maybe white sugar was what was covering it up in all the other cooked jam recipes I had tried. Whatever the reason, this is a keeper recipe!
Whats the difference between preserving and jam sugar? ›Preserving sugar differs from gelling sugar, also called jam sugar, because the latter contains pectin while preserving sugar is 100% sugar.
Which fruits are high in pectin? ›While pectin naturally occurs in fruit, the amount can vary. Fruits such as citrus, tart cooking apples, cranberries, and quince are high in pectin. Fruits such as late-season blackberries, cherries, and nectarines, are at the low end of the pectin scale.
Does stevia preserve like sugar? ›Jams and jellies that do not seal properly will spoil quicker with stevia than with sugar, since stevia does not have the same preservative properties as sugar.
Does stevia thicken like sugar? ›
There are also some things that other sweeteners can't replace. Sugar has properties that stevia does not: It browns in baking; it can thicken and take on water, and it creates what is called “mouthfeel.”
Does xylitol preserve like sugar? ›Baking Recipes
You don't have to sacrifice flavor for a low sugar or low calorie recipe. Xylitol can absorb moisture quicker than table sugar, so it's important to remember this while creating your baking masterpieces.
The AHA suggests a stricter added-sugar limit of no more than 100 calories per day (about 6 teaspoons or 24 grams) for most adult women and no more than 150 calories per day (about 9 teaspoons or 36 grams of sugar) for most men.
Why do you put a knob of butter in jam? ›Add A Knob Of Butter
To prevent scum forming on the top of your jam, add a knob of butter to your fruit at the same time as you add the sugar, we recommend 20 grams per 1 kilogram of fruit.
