If you're hosting a large party and need to cook a large batch of rice, do it in a slow cooker, or a crockpot. You'll be able to make a large amount of rice at one time and keep it warm for a few hours. Keeping cooked rice warm in a slow cooker is ideal during get-togethers when guests show up at different times. You'll always have warm rice on hand to serve up as part of a main course, such as gumbo, or as a side dish.
Cook white or brown rice in a slow cooker or crockpot following the package directions; the typical proportion is 1 cup of rice to 2 cups of water.
Add butter or margarine to taste to keep the cooked rice from sticking together.
Turn the slow cooker or crockpot off when the rice is done. Keep the cooked rice in the pot and cover it with the lid; the rice will stay warm in a slow cooker or crockpot for two to three hours.
