Instructions: How to Make Blackberry Jalapeno Jelly Recipe

Step 1: Prepare the Fruit
In a saucepan, add blackberries, jalapeños, and lemon juice. Simmer on low for 10 minutes, crushing berries gently. Strain through cheesecloth if you want a clear jelly, or keep as-is for a chunkier texture.
Step 2: Add Pectin & Boil
Return the strained (or chunky) mixture to the pot. Stir in the pectin and bring to a rapid boil over high heat, stirring continuously.
Step 3: Add Sugar & Finish Cooking
Add all the sugar at once and stir. Add butter to reduce foam. Bring to a hard boil for 1–2 minutes or until jelly begins to thicken.
Step 4: Fill Jars
Ladle the hot jelly into sterilized jars, leaving 1/4 inch headspace. Wipe rims, seal with lids, and process in a boiling water bath for 10 minutes.
Step 5: Cool and Store
Allow jars to cool undisturbed for 12 hours. Test the seals. Store sealed jars in a cool, dark place. Refrigerate after opening.
