Solar cooked brown rice comes out fine by simply mixing two parts water with one part rice in a pot and putting it in the Sun Oven. But with just a little extra effort you can give it a boost in flavor, and in my opinion, improve the texture by using the following method:
First, toss some chopped onion with a tablespoon or so of olive oil in a pot big enough to hold the amount of rice you want to make.
Place the covered pot in the Sun Oven. In a separate container, heat the water along side the onions.
When the onions are soft and the water is hot stir the rice into the pot and pour the water over it – don’t forget to use a potholder.
Cover and continue cooking until all the water is absorbed, 45 minutes to an hour. For even more flavor use chicken or vegetable broth in place of the water.
