Prep Those Peaches! Start by getting your peaches ready. You'll need to peel them, remove the pits, and then dice them up. Dice them into small pieces, maybe about ¼ to ½ inch. If you prefer a smoother jam, you can mash them slightly after dicing, but don't turn them into a complete puree.

Combine Fruit, Sugar, and Pectin. In a large bowl, combine your diced peaches, the granulated sugar, and the instant freezer pectin. Give it a good stir. Now, let it sit. Stir it occasionally over the next 10-15 minutes until the sugar is mostly dissolved. You shouldn't feel too much grittiness when you rub a little bit between your fingers.

Stir in the Lemon Juice. Once the sugar is mostly dissolved and everything looks well combined, stir in the fresh lemon juice. Give it another good mix to make sure it's evenly distributed throughout the peach mixture.

Jar It Up! Now, grab your clean jars. Freezer jam doesn't require canning, but you do need clean containers. You can use glass jars or plastic freezer-safe containers. Fill your jars, leaving about ½ inch of headspace at the top. Seal the lids tightly.

Chill and Freeze. Let the filled jars sit at room temperature for about 30 minutes or until the jam has set up nicely. Once set, you can pop any jars you plan to use in the next few weeks into the refrigerator. Any jars you want to save for later go straight into the freezer! Don't forget to label them with the date!
