Whether you’re managing diabetes, following a low-carb diet, or simply looking to reduce your sugar intake, this jam will satisfy your sweet tooth without derailing your health goals.

Why Make Sugar-Free Strawberry Jam?

• Healthier Choice: Significantly reduces your sugar intake compared to traditional jams.
• Suitable for Dietary Restrictions: Perfect for people with diabetes, those following keto or low-carb diets, and anyone looking to limit sugar consumption.
• Delicious Taste: With the right techniques and sweeteners, you can achieve a flavor that’s just as satisfying as regular jam.
• Control Over Ingredients: You know exactly what’s going into your jam, avoiding artificial preservatives and excessive sugar often found in store-bought varieties.
• Fresh and Flavorful: Homemade jam always tastes better than store-bought, especially when made with fresh, seasonal strawberries.

Ingredients You’ll Need

• Fresh Strawberries: The star of the show! Choose ripe, fragrant strawberries for the best flavor. About 4 cups (approximately 2 pounds or 900 grams) is a good starting point. Adjust the quantity based on your desired yield.
• Sweetener (Sugar-Free or Low-Sugar): This is where you have options! Here are a few choices:
  • Erythritol: A sugar alcohol that’s generally well-tolerated and has a similar sweetness to sugar. Use about 1/2 cup (approximately 100 grams) for a completely sugar-free jam.
  • Stevia: A natural sweetener derived from the stevia plant. A little goes a long way! Start with 1/4 teaspoon of powdered stevia or follow the package instructions for equivalent sweetness to 1/2 cup of sugar.
  • Monk Fruit Sweetener: Another natural sweetener with zero calories. Use according to package directions for sweetness equivalent to 1/2 cup of sugar.
  • Xylitol: Another sugar alcohol, but be cautious as it can have digestive effects in some people. Also, it is highly toxic to dogs. Do NOT use if you have pets. If used, follow the package directions.
  • Honey or Maple Syrup (Low-Sugar Option): For a low-sugar alternative, use 2-3 tablespoons of honey or maple syrup. This will add some sugar content, so adjust accordingly based on your dietary needs.
  • Agave Nectar (Low-Sugar Option): Similar to honey or maple syrup, use sparingly (2-3 tablespoons) for a low-sugar version.
• Lemon Juice: Adds acidity, which helps with setting and preserving the jam. Use 2 tablespoons of freshly squeezed lemon juice.
• Pectin (Optional but Recommended): Pectin is a natural thickening agent found in fruits. It helps the jam set properly, especially when using sugar substitutes. Use low-sugar or no-sugar needed pectin. Ball and Sure-Jell are common brands that offer suitable pectin varieties. Follow the package instructions for the amount to use, generally about 1-2 tablespoons. If you are using apples in the jam, the pectin may not be needed.
• Vanilla Extract (Optional): A teaspoon of vanilla extract enhances the flavor and adds a touch of warmth.
• Pinch of Salt (Optional): A tiny pinch of salt can balance the sweetness and bring out the strawberry flavor.

Equipment You’ll Need

• Large Pot or Dutch Oven: Use a heavy-bottomed pot to prevent scorching.
• Wooden Spoon or Heat-Resistant Spatula: For stirring the jam.
• Potato Masher or Immersion Blender (Optional): For crushing the strawberries to your desired consistency.
• Sterilized Jars and Lids: For canning the jam (see instructions below).
• Canning Tools (Optional): Jar lifter, funnel, etc., if you plan to can the jam.
• Candy Thermometer (Optional but Helpful): To ensure the jam reaches the proper setting temperature.

Step-by-Step Instructions

Step 1: Prepare the Strawberries

1. Wash and Hull: Thoroughly wash the strawberries and remove the hulls (the green leafy part).
2. Chop or Slice: Chop or slice the strawberries into smaller pieces. The size will depend on your preference for the jam’s texture. Smaller pieces will result in a smoother jam, while larger pieces will give it a chunkier consistency.
3. Weigh/Measure: Measure out the required amount of strawberries (approximately 4 cups, or adjust according to your desired yield).

Step 2: Combine Ingredients

1. In the Pot: In your large pot or Dutch oven, combine the chopped strawberries, sweetener of your choice (erythritol, stevia, honey, etc.), lemon juice, and pectin (if using).
2. Stir Well: Stir all the ingredients together until the sweetener is evenly distributed.

Step 3: Cook the Jam

1. Bring to a Boil: Place the pot over medium-high heat and bring the mixture to a full rolling boil, stirring constantly to prevent scorching. A rolling boil is one that continues even when you stir it.
2. Reduce Heat and Simmer: Once boiling, reduce the heat to medium or medium-low and continue to simmer, stirring frequently. This is where the jam will thicken.
3. Skim Foam (Optional): As the jam simmers, foam may form on the surface. Skim off any foam with a spoon for a clearer jam.
4. Cooking Time: Cooking time will vary depending on the type of sweetener used and the pectin, and moisture content of the strawberries. Generally, it takes about 20-45 minutes for the jam to thicken.
5. Use of Candy Thermometer If you use a candy thermometer it can help determine the setting point. The jam is near done when it reaches 220°F (104°C).

Step 4: Test for Setting

There are several ways to test if the jam has reached the setting point:

• Freezer Test: Place a small plate in the freezer before you start cooking the jam. To test, spoon a small amount of jam onto the cold plate and return it to the freezer for 1-2 minutes. If the jam wrinkles when you push it with your finger, it’s ready.
• Spoon Test: Dip a cold metal spoon into the jam and lift it out. If the jam drips off in a thick sheet or clumps together, it’s ready. If it runs off in a thin stream, it needs more cooking.
• Thermometer Test: As mentioned above, use a candy thermometer to check for the setting point of 220°F (104°C).

Step 5: Add Flavorings (Optional)

Once the jam has reached the setting point, remove it from the heat and stir in the vanilla extract (if using) and a pinch of salt (if using). This is also a good time to add any other flavorings you desire, such as a squeeze of lime juice or a dash of cinnamon.

Step 6: Can the Jam (Optional)

If you want to preserve the jam for longer storage, you can can it using proper canning techniques. If not canning, store the jam in the refrigerator and it will keep for about two weeks.

Sterilize Jars and Lids: Before you start, sterilize your jars and lids. There are several ways to do this:

• Boiling Water Bath: The most common method. Place the jars and lids in a large pot of boiling water for 10 minutes. Remove them carefully with tongs and let them air dry on a clean towel.
• Dishwasher: Run the jars and lids through a hot dishwasher cycle. Keep them in the dishwasher until ready to use.
• Oven: Place the jars on a baking sheet in a 250°F (120°C) oven for 20 minutes. Boil the lids in water for 10 minutes separately.

1. Fill Jars: Using a canning funnel, carefully ladle the hot jam into the sterilized jars, leaving about 1/4 inch of headspace (the space between the jam and the top of the jar).
2. Remove Air Bubbles: Use a clean utensil (like a chopstick or spatula) to gently release any trapped air bubbles from the jam.
3. Wipe Rims: Wipe the rims of the jars clean with a damp cloth.
4. Place Lids and Rings: Place the sterilized lids on the jars and screw on the rings until fingertip-tight (not too tight).
5. Process in a Boiling Water Bath: Place the filled jars in a boiling water bath canner, ensuring that the water covers the jars by at least 1 inch. Bring the water to a rolling boil and process for 10 minutes for half-pint (8-ounce) jars and 15 minutes for pint (16-ounce) jars. Adjust processing time for altitude (add 5 minutes for every 1,000 feet above sea level).
6. Cool and Check Seals: Carefully remove the jars from the canner with a jar lifter and place them on a towel-lined surface to cool completely. As the jars cool, you should hear a popping sound as the lids seal. After the jars have cooled completely (about 12-24 hours), check the seals by pressing down on the center of the lid. If the lid doesn’t flex or pop back up, it’s properly sealed. If the lid flexes, the jar is not sealed and should be reprocessed with a new lid or stored in the refrigerator.

Step 7: Store and Enjoy

• Canned Jam: Properly canned jam can be stored in a cool, dark place for up to 1 year.
• Refrigerated Jam: Uncanned jam should be stored in an airtight container in the refrigerator for up to 2 weeks.

Enjoy your homemade sugar-free or low-sugar strawberry jam on toast, muffins, scones, yogurt, oatmeal, or as a topping for desserts. It’s a delicious and healthy way to enjoy the taste of summer all year round!

Tips and Variations

• Adjust Sweetness: Taste the jam as it cooks and adjust the amount of sweetener to your liking. Remember that the flavor will intensify as the jam cools.
• Add Spices: Experiment with different spices like cinnamon, nutmeg, or ginger for a warm and comforting flavor.
• Combine Fruits: Try adding other fruits like raspberries, blueberries, or peaches for a mixed berry jam.
• Use Frozen Strawberries: If fresh strawberries are not available, you can use frozen strawberries. Thaw them completely before using and drain off any excess liquid.
• Chia Seeds for Thickening: If you prefer not to use pectin, you can add chia seeds for thickening. Add 1-2 tablespoons of chia seeds to the jam during the last 10 minutes of cooking and stir well. Let the jam sit for a few minutes after cooking to allow the chia seeds to fully absorb the liquid.
• No-Cook Chia Seed Jam: For an even simpler method, you can make a no-cook chia seed jam. Combine mashed strawberries, sweetener, lemon juice, and chia seeds in a jar. Stir well and refrigerate for at least 2 hours, or overnight, to allow the chia seeds to thicken the jam. This version won’t have the same cooked flavor as traditional jam, but it’s a quick and easy option.
• Apple Sauce: You can use some unsweetened apple sauce in combination with other fruit to create delicious jam. It enhances the sweetness of the jam, and is perfect for when you want to use less sweeter or strawberries.

Troubleshooting

• Jam is Too Runny: If the jam doesn’t set properly, it may not have been cooked long enough. Return the jam to the pot and cook for a few more minutes, testing for setting again. Alternatively, you can add a bit more pectin or chia seeds.
• Jam is Too Thick: If the jam becomes too thick, add a tablespoon or two of water or lemon juice and stir well.
• Jam is Scorching: To avoid scorching, use a heavy-bottomed pot and stir the jam frequently, especially as it thickens.
• Mold Growth: Improperly canned jam can develop mold. Always follow proper canning techniques to ensure a safe and shelf-stable product. Discard any jam that shows signs of mold.
