1. Disinfecting and Deodorizing Sponges

Don't throw out the kitchen sponge that smells like last night's salmon. Soak it in water spiked with white vinegar or lemon juice, then heat it on high for 1 minute. (Use an oven mitt when you remove it.) This will also disinfect any sponges you used to wipe up the juices from a raw chicken.

2. Cooking an Entire Dinner in Under 10 Minutes

And we don't mean the TV variety. We mean braised salmon with green beans and mashed potatoes. Use the microwave for any recipe that calls for braising, poaching, or steaming. Just subtract about three-quarters of the cooking time. Remember to stir liquids often to redistribute the heat, and always take the food out a minute or two before it's completely done, since it will continue to cook.
