You only need three ingredients to make these delightful homemade strawberry preserves, two pounds of strawberries, granulated sugar, and lemon juice. This allows the flavor of the berries to really shine. Another bonus: making jam or preserves is a great way to use up less than perfect fruit. This recipe can be doubled or tripled to make a larger batch of jam. If you want the preserves to last longer than three weeks in the refrigerator, you'll need to process the jars in in a hot water canning bath.
