Not only is it fast, but your microwave is the kitchen's undisputed efficiency champ. That's because its energy goes straight into heating the food, not the air or a pan which surrounds it.
This is good news if you're keeping a close eye on that power bill during warm weather months. Invest in a microwave cookbook and make sure you have a good selection of microwave-safe casseroles and dishes. Combination convection/microwave are an even better idea.
Save money while keeping cool in the kitchen!
