Making Sweet Heat Peach Pepper Jelly involves a few precise steps, and following them closely will help ensure a properly set, well-balanced jelly.

Step 1: Prep the Fruit and Peppers

Wash, peel, and finely chop the peaches. Finely dice the bell peppers and jalapeños, and mince the habanero if using. Chopping everything finely and to a consistent size helps ensure even cooking and a pleasant texture throughout the finished jelly.

Step 2: Combine and Cook

Place the peaches, bell peppers, jalapeños, apple cider vinegar, lemon juice, and water into a large saucepan over medium-high heat.

Step 3: Soften the Fruit

Bring the mixture to a gentle boil, stirring frequently, and cook for about 8 to 10 minutes until the peaches soften.

Step 4: Add the Pectin

In a small bowl, combine the powdered pectin with a few tablespoons of the sugar to help prevent clumping, then stir it into the fruit mixture.

Step 5: Bring to a Full Boil

Bring the mixture to a full rolling boil, one that continues bubbling even while being stirred.

Step 6: Add the Remaining Sugar

Add the remaining sugar all at once and stir continuously until completely dissolved.

Step 7: Hard Boil

Return the mixture to a hard boil and cook for 1 to 2 minutes, stirring constantly. This step is essential for properly activating the pectin and ensuring the jelly sets correctly.

Step 8: Reduce Foam

If desired, stir in the butter to reduce any foam that forms on the surface, resulting in a clearer, more attractive finished jelly.

Step 9: Skim and Remove from Heat

Remove the saucepan from the heat and skim off any excess foam from the surface.

Step 10: Jar the Jelly

Carefully ladle the hot jelly into clean, sterilized jars, leaving about 1/4 inch of headspace at the top of each jar.

Step 11: Seal and Process

Seal the jars immediately and allow them to cool completely, or process them in a boiling water bath for 10 minutes if canning for long-term pantry storage.

Step 12: Let It Set

Allow the jelly to rest for at least 24 hours before serving so it fully sets and the flavors have time to develop and meld together.
