I've been wanting to get a rice cooker for ages now. After finding this recipe on a friend's blog, I'm so glad I never got around to it. This really works.
Take 2 white cups rice, 4 cups water and 2 teaspoons vinegar, put them in a microwave safe dish. Cover the dish tightly with plastic wrap and microwave for 20 minutes.
That's it. It's amazing. No really. Go try it.
