Ingredients
  

  • 5-6 medium peaches ripe, peeled, pitted, and finely chopped
  • 4-5 small jalapenos finely chopped, adjust quantity and remove seeds/membranes for desired heat level
  • 1 Tablespoon lemon zest
  • 2 Tablespoons lemon juice
  • 3 cups granulated sugar

Equipment

  • Large, heavy-bottomed saucepan or pot
  • Glass jars and lids

Method
 

  1. Step 1: Prep Your Fruit & Peppers: Peel, pit, and finely chop the peaches. For easy peeling, dip peaches in boiling water for 30 seconds, then plunge into ice water. Wash jalapenos and finely chop. For less heat, remove all seeds and white membrane. Wear gloves when handling jalapenos.
  2. Step 2: Combine and Heat: In a large, heavy-bottomed saucepan or pot, combine chopped peaches, chopped jalapeños, lemon zest, and lemon juice. Place over medium-high heat. Stir frequently and bring the mixture to a gentle boil.
  3. Step 3: Add Sugar and Boil: Once the fruit mixture reaches a full, rolling boil, add the 3 cups of granulated sugar. Stir constantly until the sugar is completely dissolved. Maintain the full rolling boil and cook for about 15–20 minutes, stirring occasionally, until the jam thickens and sets.
  4. Step 4: Check for Doneness: To test if the jam is ready, carefully dip a metal spoon into the hot jam. Lift the spoon out and let the jam cool slightly on the back. If it coats the spoon and drips off slowly or forms a sheet, it's ready. If too thin, continue boiling and re-test in a few minutes. (Alternatively, spoon a small amount onto a plate chilled in the freezer, let sit 30 seconds, then push - it should wrinkle and set).
  5. Step 5: Jar It Up: Wash glass jars and lids in hot, soapy water and dry thoroughly. Carefully ladle the hot jam into the clean jars, leaving about ¼ inch of headspace at the top. Wipe the rims clean with a damp towel and place the lids on tightly. As the jars cool to room temperature, a vacuum seal may form. For long-term shelf-stable storage, proper water bath canning is required.

Notes

Using perfectly ripe peaches is key for best flavor and set. Adjust the spiciness by controlling the amount of jalapeno seeds and membranes; a tiny pinch of cayenne can be added for extra heat if desired. The rolling boil is essential for thickening. Ensure jars are clean to prevent spoilage. For short-term storage (2-3 months), keep jars in the refrigerator. For long-term, shelf-stable storage (up to a year), process filled jars in a boiling water bath according to standard canning procedures.
