Directions

1. Sterilize the Jar: Bring a large pot of water to a boil. Submerge your mason jar and lid for a few minutes to sterilize. Carefully remove and dry completely.

2. Prep the Strawberries: Remove the green tops from the strawberries and dice them into small pieces. For a smoother jam, puree the strawberries in a blender, or leave them chunky for a rustic texture.

3. Combine Ingredients: In a large pot or deep saucepan, combine the diced strawberries, lemon juice, and sugar. Stir well, making sure the berries are completely coated with sugar.

4. Let the Mixture Rest: Let the mixture sit for 10–15 minutes, allowing the sugar to draw out the juices from the strawberries, creating a syrupy base for your jam.

5. Dissolve the Sugar: Turn the heat to medium-low. Stir the mixture with a rubber spatula until all the sugar is dissolved. Scrape down the sides of the pot to prevent sugar crystals from forming.

6. Simmer and Mash: Let the mixture simmer for 10–15 minutes, stirring frequently. Mash the strawberries gently with a potato masher to achieve your desired consistency.

7. Boil the Jam: Increase the heat to bring the mixture to a rolling boil. Stir constantly, and continue boiling until the jam reaches 220°F (use a candy thermometer for accuracy).

8. Finish and Jar: Remove the pot from heat and skim off any foam from the surface. Pour the hot jam into your prepared jar, leaving about ¼ inch of space at the top. Seal the jar and let it cool to room temperature.

FAQs

Why is lemon juice necessary in strawberry jam?

Lemon juice helps the natural pectin in strawberries to gel, allowing the jam to set. It also adds a bright, tangy flavor that balances the sweetness.

Can I use frozen strawberries instead of fresh?

Yes, you can use frozen strawberries. Be sure to thaw and drain them well before using them in the recipe.

How do I know when my jam is ready?

The jam is ready when it reaches 220°F or passes the “chill test.” To do this, place a spoonful of jam on a cold plate, wait a minute, and then run your finger through it. If it wrinkles and holds its shape, it’s done.

Can I store the jam for long-term use without refrigeration?

This recipe is intended for short-term storage in the fridge. If you want to can it for long-term storage, follow a certified canning guide to ensure safety.

Will my jam thicken more as it cools?

Yes, the jam will continue to thicken as it cools, so don’t worry if it appears a little loose when it’s still hot.

Can I make this jam without sugar?

Sugar is essential for the jam’s texture and preservation, but you can experiment with alternative sweeteners such as honey or agave syrup, though the texture may differ.

How do I prevent the jam from crystallizing?

Ensure that all sugar is fully dissolved during the cooking process. Stir the mixture constantly and scrape the sides of the pot to prevent undissolved sugar crystals.

Can I use other fruits to make jam?

Yes, you can substitute strawberries with other fruits such as raspberries, blueberries, or peaches. Just adjust the sugar content according to the fruit’s natural sweetness.

How do I store leftover jam?

Store leftover jam in an airtight container in the fridge. Use a clean spoon each time to avoid contamination and extend its shelf life.

Can I adjust the sweetness of the jam?

Yes, you can reduce the amount of sugar to make the jam less sweet, but keep in mind that sugar is also responsible for helping the jam set properly.
