Capture the glorious peach flavor and keep it around long after peach season is over with this super simple peach freezer jam recipe. It's so quick and easy, and the fresh, bright taste is absolutely heavenly.
Tips for success include using ripe but firm peaches, measuring accurately (especially pectin and sugar), vigorously stirring for 3 minutes after adding sugar until dissolved, using clean jars, and leaving ½ inch headspace when filling jars, especially for freezing. Jam can be stored in the refrigerator for up to 3 weeks or frozen for up to 1 year (thaw in fridge for ~24 hours). Can substitute with other fruits like strawberries or berries (check pectin amounts). Adding spices like cinnamon or ginger is an option. Reducing sugar is not recommended with this pectin type as it's crucial for setting. Frozen peaches can be used if thawed and drained. Recipe requires instant freezer pectin, not liquid pectin. Runny jam usually means sugar wasn't dissolved or wrong/too little pectin was used.
