Step-by-Step Instructions
- Start by sterilizing your jars in simmering water at approximately 180°F for about 10 minutes.
- In a deep pot, mix together blackberries, sugar, jalapenos, and lemon juice. Stir gently.
- Lightly mash the blackberries with a potato masher, then place the pot over medium heat and stir continuously until it reaches 220°F.
- Perform the wrinkle test on a cold plate to check for doneness; if it wrinkles, your jam is ready.
- Ladle the hot jam into prepared jars, leaving 1/4 inch headspace, and wipe the rims for a clean seal.
- Allow jars to cool to room temperature for about 30 minutes before sealing and refrigerating.
