Use Ice Cube Trays to Freeze Broth, Pesto, and Tomato Paste

Most recipes call for a tablespoon or two of tomato paste, a splash of broth, or a spoonful of pesto — not the whole container. Pour the leftovers into ice cube trays and freeze them. Once solid, pop the cubes out and transfer them to a freezer bag.

Each cube is roughly one to two tablespoons — a perfect portion for cooking. You will never again throw away half a can of tomato paste or watch a jar of pesto grow mold in the back of the fridge. This works equally well for coconut milk, wine, herb butter, and citrus juice.
