When cooking rice in a solar cooker, one uses less water than on a conventional stove since none of the water is lost during the cooking process.

2 cups Rice

3 cups water

Cooking white rice in unsalted water is common in South-East Asia and keeps the flavour of the rice. Take 2 cups of rice and wash it (if your rice needs washing. White rice sold in the USA and Europe should not be washed.) Heat 3 cups of water until small bubbles appear (approx. 90 degrees C). Put the washed rice into the water. Leave it in the solar cooker for 10-20 minutes. Take the pot out of the solar cooker and keep it warm, e.g. in an insulated box or covered with many blankets. Ready to serve after another 10 to 15 minutes.

The mentioned amounts are to be taken by volume, not weight. This means for example 2 cups of rice to 3 cups of water for about 6 persons. Or: 1 cup of rice to 1 1/2 cups of water to feed about 3 persons. Recipe works best in a box cooker; the rice could stick on the walls of the pot if a powerful parabolic cooker is used. It is useful to take a heavy pot instead of a light one because of the heat storage in the metal.

Cook brown rice using the same proportions. Just add the rice to the cold water. Heat until boiling in the solar cooker. If you want to use heat-retention cooking, keep the rice in the solar oven for 10-15 minutes before putting the pot into an insulated box. Otherwise keep the rice in the solar cooker until it is done.
