Prep the peaches. Bring a pot of water to a boil. Score a shallow X on the bottom of each peach, blanch 30–45 seconds, then move to an ice bath. Slip off the skins, pit, and chop. If you like a smoother jam, chop finely; for chunkier jam, go larger.

Mac­erate for juiciness. In a large, wide pot, combine peaches, honey, lemon juice, zest (if using), and salt. Stir and let sit 15–20 minutes until the fruit releases juice. This helps dissolve the honey and prevents scorching.

Start the simmer. Set the pot over medium heat and bring to a steady simmer, stirring often. Once bubbling, reduce to medium-low so it stays lively but not aggressive. Skim any light foam that gathers on top for a clearer finish.

Break down the fruit. After 10–15 minutes, use a potato masher to gently smash the peaches to your preferred texture. Keep simmering, stirring frequently so the bottom doesn’t stick.

Cook to the set you like. Continue simmering 25–35 minutes total, until the jam thickens and a spoon dragged across the bottom leaves a brief line. For a firmer set, cook a touch longer. For a looser, spoonable jam, stop earlier.

Test for doneness. Chill a small plate in the freezer. Drop a spoonful of jam on the cold plate and wait 30 seconds. Push it with your finger. If it wrinkles and holds a soft mound, it’s done. If it runs, cook 5 more minutes and test again.

Finish the flavor. Off the heat, stir in vanilla, cinnamon, or ginger if you like. Taste and adjust with a squeeze of lemon for brightness or a drizzle more honey for sweetness.

Jar it up. Ladle hot jam into clean, warm jars, leaving about 1/4 inch headspace. Wipe rims and seal. For refrigerator jam, cool to room temperature, then chill. For shelf-stable storage, process jars in a boiling water bath for 10 minutes, adjusting for altitude as needed.
