How to make fruit jam without sugar

1 to 1. That’s the average ratio of fruit to sugar in most jam recipes (commercial and homemade). I’m not going to lie, your standard jar of sugary homemade jam tastes divine, but do we really need to be starting our day with that much sugar? Is that really much better than handing my kids a donut for breakfast?

Myth – You need sugar to preserve the fruit.

Sugar affects the acidity that is crucial for safe canning. All fruits that are safe to water bath can with sugar are safe to water bath can without. I promise. All you need to do is add more lemon juice to boost the acidity. The number one rule of canning (unless you are a seasoned pro) is to follow a trusted recipe to the letter. I do not consider myself a seasoned pro, so it’s tested recipes for me – most of the time. Don’t worry, I’ll share my favorites in just a moment.

Sugar-free jams take longer to process, so again, follow those recipes! If you’re new to canning, you might want to check out my water bath canning FAQs.

Myth – Your jam won’t gel without sugar or sweetener.

There is a misconception that your jam won’t gel without sugar. While that’s technically true, there are tricks to make your jam jammier without sugar. There are several no-sugar pectins available on the market: Ball and Dutch Jell. There is also Pomona, which uses calcium to create gelling. I really like Pomona’s pectin, but it takes an extra step to use and might not be right for a beginner. 

Simply Canning has a great real-world review on using Pomona’s Pectin worth looking at. Do not use inversion or open kettle canning!

Myth – Fruit takes on a weird color when you can it without sugar.

Sugar does keep fruit bright and colorful, but there are ways to keep your jam pretty without the use of sugar. Starting with the proper fruit is the first and most important step. Make sure your fruit is just reaching ripeness when you preserve it. This isn’t the time to use up those overripe strawberries you forgot you had. You want to use firm fruit.

You can slow down fruit darkening by using a lemon juice or citric acid bath. Citric acid sounds scary and very unnatural, but it is a commonly used natural ingredient.

Citric acid is a very useful and effective preservative, obtained from naturally occurring organic acids. It exists in many different fruits and vegetables but is especially concentrated in lemons and limes. – Mountain Rose Herbs

To create a bath for your fruit, mix 3/4 cup lemon juice (or 1 teaspoon citric acid) to 1 gallon of cool water. Add your cut up fruit and give it a swirl around in the water for a bit. Once you’re sure all the fruit has been “washed” you can drain the water and proceed with processing.

My favorite Sugar-Free Jam Recipes

I washed my berries in a citric acid wash (except for the raspberries and grapes) before following these recipes.

Raw Raspberry 5-Minute Jam

This recipe is a short-use jam that can’t be canned, but it’s great if raspberries are in season. It uses chia seeds to thicken. If you haven’t worked with chia seeds before, it absorbs fluids and turns into a jelly. Plus, chia seeds are loaded with fiber, protein, Omega-3 fatty acids and various micronutrients. Yay for the healthy boost!

Truly Sugar-Free Strawberry Jam

Strawberries are naturally sweet, so why mess with Mother Nature? This recipe is also for short-term use, but it lasts up to two months in the refrigerator in an air-tight container. Arrowroot powder is used to thicken the jam.

No Sugar Apricot Jam

I spent a long time thinking I didn’t like apricot jam. It was so sickeningly sweet! You know what this one tastes like? Fresh apricots – which apparently I really like. She uses Sure-Gel pectin in her recipe. I haven’t used that one, but I did have success using the Ball pectin I had on hand. She didn’t can hers, but I canned mine (I know, do as I say, not as I do). I processed for 15 minutes. 

Sugar-Free Blackberry Jam

This gem was found in an article about sugar alternatives, but this particular recipe uses fruit juice to sweeten it. Apple juice is naturally sweet. Again it doesn’t give canning instructions, but I totally did (don’t stone me!)

Concord Grape Jelly: Sugar-Free

Yes, you read that right. Jelly! I know we’re all about jams, but I had to include this one. I didn’t think there was any way to get juice (the basis of jelly) to set up without sugar. Boy, was I wrong. She uses an apple (which contains natural pectin) and Pomona’s for this recipe. Scroll down to see her jelly standing at attention on a piece of toast.

For more great recipes I suggest checking out Preserving with Pomona’s Pectin. It’s not strictly sugar-free. There are many low-sugar or sugar-substitute recipes in there, but it’s also got some sugar-free gems.

Newsletter and Keto Free Ebook

Spread it over our Keto Farmers Bread, Waffles, Pancakes, Crepes, Brioche Bread Loaf, or Challah Bread. 

Add into a Homemade Greek Yogurt or Curd Cheese topped with a few of the fresh berries, and you have just accomplished the best tasting Keto Breakfast that will fill you up the whole morning.  

Those are only a few ideas that come into my mind when thinking of what to use this healthy jam for. 

Sugar Free Jam

Our Recipe for no sugar added jam can be made with any berries that fit into our lifestyle. 

Be it Blueberries, Raspberries, Blackberries, Red currants, Gooseberries, Black currants, or Wild Berries, or you can even add a Rhubarb for that slightly sour flavor. 

Although I have already made Cranberry Sauce using a different method together with Brown Sugar Sweetener, you can easily use Cranberries with this recipe as well. 

Making Strawberry Jam has never been easier. Trust me. And this is from a person who has  never made preserves, jams, jelly, marmalade canning, or anything longer than 10 minutes in the kitchen. 

Do you wonder how I make this Keto Jam super thick without pectin or any other thickening agent?

Chia seeds

Chia seeds are our secret ingredient. 

They are available everywhere, and I am sure you all have a bag at home. Chia Seeds are super easy to store and great ways to use in so many recipes in our low-carb lifestyle. 

The main purpose of chia seeds is to thicken your dish without adding anything else. Like the Flax Seeds, once mixed with liquid, each seed will form a jelly-like structure, making your final dish perfectly thick. 

Uses for Chia Seeds

I have already made a few puddings using chia seed, as this is the healthiest, quickest, and easiest option when thickeners are concerned. 

You can pick from our beautiful Rainbow Chia Pudding, which I love to make when we have guests, Dalgona Pudding when coffee is needed, Chocolate Chia Seeds Pudding, or the quickest breakfast ever, creating a Coconut Pudding when in a hurry.

Chia Strawberry Jam

Our Chia Strawberry Jam is a recipe that nobody can ever get wrong. 

Added to this, I love the texture of the seeds inside this no sugar jam, as strawberries or raspberries also contain tiny seeds you can taste, and those are, to me, identical to chia. 

Depending on your preference, you can use ground Chia Seeds as well. 

Low Sugar Strawberry Jam Recipe

Our recipe only contains the natural fruit sugar the actual strawberries contain. 

Depending on your sweetness buds, you can add one of the sweeteners if needed. 

But I believe this Sugar-Free Strawberry is already sweet enough and does not need anything else to sweeten it further.

Type of Strawberries

There is also a big difference between the season and the type of strawberries you will use. 

Store-bought strawberries do not have so much of a taste throughout the winter and therefore might be sweetened a bit. 

They also have more water content, which needs to be cooked longer and considered once calculating your macros. 

But when it comes to the summer, and you get your own, handpicked or bought from one of the fields close to you, this jam without sugar or sweetener will be so sweet, one would not believe it. 

More ripe your strawberries are, the sweeter your keto strawberry jam is. 

How many Carbs are in Sugar-Free Strawberry Jam?

In our jam recipe, strawberries are the only sweetener involved, and therefore the carbohydrate content is really minimal.I have split the calculation for you into 10 servings, where a serving is 2 tablespoons of this Diabetic Jam. 

You get a perfect 3 grams of carbohydrates only together with 1 gram of Fiber for a portion. This brings you to a total of 2 grams of net carbs for two tablespoons of homemade sugar-free strawberry jam.
