Many recipes call for unwaxed citrus fruit, especially if you are zesting the skin. But finding unwaxed fruit at your supermarket can be impossible. Growers spray wax to protect the fruit and to give it a sheen so it looks good in stores; while considered safe to eat, many people prefer to avoid it. To remove the wax at home, just microwave a lemon or orange for 20 seconds; use a brush to remove the melted wax. Rinse and wipe with a clean towel, and you'll be good to go.
