Peach Pie Filling

This is the canning project that pays back from the first jar opened in February. Twelve cups of fresh peaches cook down with chopped apples, golden raisins, lemon juice, and a cheesecloth-tied spice bag of cinnamon and cloves until thickened, then go straight into pint mason jars and a 15-minute boiling water bath. Four pints come out of one batch, and each pint holds enough filling for a single 8-inch pie.

Vinegar might raise an eyebrow on first read, but it pulls weight here. The acid balances the natural sweetness of the peaches and ensures safe acidity for water-bath canning, which only works on high-acid foods. Apples thicken the filling naturally as their pectin breaks down during the long simmer; raisins add chew and a different kind of sweetness. The classic move when you finally crack a jar months later: stir 2 tablespoons of cornstarch into the room-temperature filling before pouring into a crust, since canning softens the apple pectin.

Pro Tips

• Blanch the peaches in boiling water for 30 seconds, then plunge into ice water. The skins slip off in one piece.
• Use a stainless steel or enamel pot. Aluminum reacts with the lemon and vinegar and discolors the filling.
• Wipe each jar rim before sealing. Sticky residue prevents a clean seal, and an unsealed jar won’t hold long-term.
• Listen for the lid pop within 24 hours. Unsealed jars need to go in the fridge and be used within a week.

Variations

• Swap dried cranberries for the raisins for a more tart, less sweet filling.
• Add a split vanilla bean to the spice bag for a floral, aromatic depth.
• Use white peaches for a more delicate, less sun-bright color and flavor in the finished pie.
