You can freeze all kinds of things for use in drinks and sauces. I freeze a tray of grapes to spruce up the look and fun of summer cocktails. And I always make a double batch of pesto, freezing half of it in ice cube trays. I pop a square or two into soups, onto grilled fish, or into the stove-top pan to make an instant sauce.
