Ingredients
  

Main Ingredients
  • 3 cups ripe peaches, peeled and finely chopped Use ripe peaches for best sweetness.
  • 1 piece red bell pepper, finely diced
  • 1–2 pieces jalapeños, finely minced, seeds removed for milder heat Remove seeds for gentler heat.
  • 1½ cups granulated sugar Can adjust for less sugar.
  • 2 tablespoons lemon juice Fresh lemon brightens the jam.
  • 1 teaspoon lemon zest
  • ½ teaspoon salt
  • ½ teaspoon crushed red pepper flakes (optional)

Method
 

Preparation
  1. Add the peaches, red bell pepper, jalapeños, sugar, lemon juice, lemon zest, salt, and crushed red pepper flakes into a large saucepan over medium heat. Stir everything so the sugar begins to dissolve.
  2. Wait for the mixture to come to a gentle bubble; you’ll hear a soft sizzle and see steam rise.
  3. Reduce the heat so the pot simmers. Stir often to stop sticking, and mash a few peach chunks with your spoon for body.
  4. Note the aroma: the jam should smell fruity and warm, with a bit of pepper spice. After about 20 minutes it will start to thicken at the edges.
  5. Continue simmering for about 10–15 more minutes, stirring more frequently toward the end; the jam is done when it coats the back of a spoon and drips slowly. Look for glossy, slightly reduced volume and golden edges.
  6. Remove the pan from the heat and let it cool for 10 minutes. Transfer to clean jars and refrigerate once fully cool.

Notes

For a firmer set, simmer a few minutes longer. Time-saver: Peel peaches quickly by blanching 30–60 seconds; skins slip off easily. Common mistake + fix: If your jam is too thin, simmer a bit longer and mash some fruit to help thicken. Simple variation: Stir in a teaspoon of fresh thyme at the end for herbaceous warmth.
