Quickly and easily steam edamame or other vegetables such as broccoli, green beans, and more, with this Japanese microwave steamer. To use, place a small amount of water in the bottom of the shallow part of the steamer. Set the perforated basket over the water, and place your vegetables on top. Line up the slots on the top lid with the slots on the bottom part of the steamer. This is where the steam will escape, so be sure the slots are open. Place the steamer in the microwave for 30 seconds to 1 minute, depending on how you like your vegetables steamed. The steamer is the perfect size for 1-2 servings, and is small enough to pack in a lunch box.
