Don’t let leftover wine go to waste! Make your own wine cubes for cooking or mixing instead. Simply pour any excess into a plastic ice-cube tray, and when a recipe calls for wine, pop in a frozen cube or two. You can use the same approach with broth, fruit juices, tomato sauce, and even coffee. Try this versatile trick with herbs, too, so you'll always be able to add a punch of fresh flavor to soups or stews: Chop up herbs, place them in ice-cube trays, cover with water, and freeze. When you're ready, simply slide some cubes onto your skillet to melt the ice, then retrieve the herbs to fill your dishes with deliciousness.
