Strawberry Refrigerator Jam
Why This Recipe Works
Refrigerator jams generally make a small batch, which means you don’t need to invest in bushels of fruit and there’s no need for canning equipment to sterilize the jars for long-term storage; you can keep the one or two jars of jam the recipe makes in the fridge and finish them off in a few weeks. We use a small amount of fruit so that it will cook down quickly to the proper consistency, and the less you cook fruit, the more of its fresh taste is preserved. A shorter cooking time also preserves more of the naturally occurring pectin in the fruit, which is necessary for proper gelling. In addition to the fruit’s pectin, we tinkered with the amounts of lemon juice and sugar to be sure that the jam would set properly, since acidity and sugar help pectin form a strong gel without the need for adding commercial pectin.
