Cooking rice can be quite simple! Generally, you'll want to rinse the rice first to remove excess starch. Then, use a 1:2 ratio of rice to water (e.g., 1 cup of rice to 2 cups of water). Bring the water to a boil, add the rice, reduce the heat to low, cover, and simmer for about 18 minutes. Let it sit off the heat, still covered, for 5 minutes to steam.
Do you have a particular type of rice in mind, or any specific challenges you've faced with cooking rice?
