Homemade Blackberry Jam
- 16 oz fresh blackberries (~4 cups)
- 1.75 cups granulated sugar
- 1/2 Tbsp lemon juice
- 2 Tbsp cornstarch
- 2 Tbsp water
- Wash berries and place them in a medium saucepan over low heat. Once the berries are warm, muddle them in the saucepan until no large pieces remain. (Optional: Use a food mill at this point to deseed the mixture.)
- Add the sugar and lemon juice; stir until well combined.
- Using a separate bowl, mix the cornstarch and water until well combined. Add this mixture to the saucepan; stir until well combined.
- Increase heat to medium-low, and bring to a boil. Stir frequently to ensure jam doesn’t burn.
- Once the jam reaches 220°F degrees (~15-20 minutes), remove it from the heat and allow it to cool at room temperature. (If needed, you can skim and discard any foam that may be on top.)
- Once cool, store in an airtight container in the refrigerator.
