This low sugar no sugar strawberry jam is perfect for those looking to enjoy the sweet taste of strawberries without the added sugar. It's a simple and healthy alternative to traditional jams, making it a great choice for anyone watching their sugar intake.
One ingredient you might not have at home is pectin. This is a natural thickening agent often used in jams and jellies. You can find it in the baking aisle of most supermarkets. Make sure to pick up freshly squeezed lemon juice as well, as it adds a necessary acidity to the jam.

Ingredients For Low Sugar No Sugar Strawberry Jam
Strawberries: Fresh, hulled, and mashed to create the base of the jam.
Water: Helps to cook down the strawberries and achieve the right consistency.
Lemon juice: Adds acidity and helps in the gelling process.
Pectin: A natural thickening agent that helps the jam set.
Technique Tip for Making Strawberry Jam
When making this strawberry jam, ensure that the pectin is thoroughly mixed in to avoid clumping. Stir constantly when adding the lemon juice and pectin to achieve a smooth consistency. Additionally, use a masher or immersion blender to break down the strawberries evenly, which helps in achieving a uniform texture.

How to Store or Freeze Your Strawberry Jam
Ensure your jars are sterilized before storing the jam. This can be done by boiling them in water for 10 minutes or running them through a hot cycle in the dishwasher.
Once the jam is cooked and still hot, carefully pour it into the sterilized jars, leaving about ¼ inch of space at the top.
Wipe the rims of the jars with a clean, damp cloth to remove any jam residue that could prevent a proper seal.
Place the lids on the jars and screw on the bands until they are fingertip tight.
Allow the jars to cool at room temperature. As they cool, you should hear a popping sound, indicating that the jars have sealed properly.
Store the sealed jars in a cool, dark place like a pantry or cupboard. Properly sealed jars can last up to a year.
For opened jars, keep them in the refrigerator and use within 3-4 weeks to ensure the best flavor and quality.
If you prefer to freeze your strawberry jam, make sure to use freezer-safe containers or jars.
Leave about ½ inch of headspace in the containers to allow for expansion as the jam freezes.
Label the containers with the date and contents before placing them in the freezer.
Frozen jam can last up to a year, but for the best taste, try to use it within 6 months.
When you're ready to use the frozen jam, thaw it in the refrigerator overnight. Stir well before serving to ensure an even consistency.
How to Reheat Leftovers
Stovetop Method: Place the jar of strawberry jam in a pot of simmering water. Heat gently until the jam reaches your desired temperature. This method ensures even heating without altering the texture.
Microwave Method: Transfer a portion of the strawberry jam to a microwave-safe bowl. Heat on medium power in 15-second intervals, stirring in between, until warm. Be cautious not to overheat, as it can cause the jam to become too runny.
Double Boiler Method: Set up a double boiler by placing a heatproof bowl over a pot of simmering water. Add the strawberry jam to the bowl and stir occasionally until warmed through. This gentle method helps maintain the jam's consistency.
Oven Method: Preheat your oven to 250°F (120°C). Place the jar of strawberry jam in an oven-safe dish and cover with aluminum foil. Heat for about 10-15 minutes, checking occasionally to ensure it doesn't overheat.
Toaster Oven Method: If you have a toaster oven, preheat it to a low setting (around 200°F or 95°C). Place the jar of strawberry jam inside and heat for 10-15 minutes, stirring halfway through to ensure even warming.
Hot Water Bath Method: Submerge the sealed jar of strawberry jam in a bowl of hot water for about 5-10 minutes. This method is quick and effective, especially if you need to reheat a small amount.
Best Tools for Making Strawberry Jam
Saucepan: A large, deep pan used for cooking the strawberries and water mixture over medium heat.
Measuring cups: Used to accurately measure the 4 cups of hulled and mashed strawberries and 1 cup of water.
Measuring spoons: Essential for measuring the 1 tablespoon of freshly squeezed lemon juice and 1 tablespoon of pectin.
Wooden spoon: Ideal for stirring the mixture to ensure even cooking and to prevent sticking.
Ladle: Useful for transferring the hot jam into sterilized jars without making a mess.
Sterilized jars: Necessary for storing the finished jam to keep it fresh and safe for consumption.
Jar lifter: Helps in safely handling the hot sterilized jars to avoid burns.
Funnel: Assists in pouring the jam into the jars without spilling.
Potato masher: Used for mashing the strawberries before cooking.
Timer: Handy for keeping track of the cooking and simmering times to ensure the jam is cooked perfectly.
How to Save Time on Making Strawberry Jam
Use a food processor: Quickly mash the strawberries by pulsing them in a food processor instead of mashing by hand.
Pre-measure ingredients: Have all ingredients like water, lemon juice, and pectin pre-measured and ready to go before you start cooking.
Sterilize jars in advance: Sterilize your jars and lids ahead of time so they are ready when the jam is done.
Use a wide saucepan: A wide saucepan allows for faster evaporation and reduces cooking time.
