Ingredients 2 pounds peaches 3 cups sugar 1 tablespoon fresh lemon juice Directions Peel, pit, and cut peaches into 1/2-inch chunks. Combine with 1/4 cup water in a large saucepan; bring to a simmer. With a potato masher, mash into a coarse puree. Simmer, stirring often, 10 minutes. Stir in sugar until dissolved. Bring to a boil; reduce heat, and simmer, stirring often, about 15 minutes. (Test doneness by spooning some jam onto a plate; when you run your finger through it, a trail should stay for a few seconds.) Skim foam from surface; stir in fresh lemon juice. Let cool. Cook's Notes Cool jam completely before ladling it into clean glass jars. Rate it Print
