I am quite proficient at cooking rice in a 1-2 qt pot. But, when I need 3-5 lbs at a time, I can't find my way to hot water. I've tried several different approaches on these amounts, but no luck. I always come out with a mix of mush and uncooked rice. Is there a secret without a rice steamer? I don't want to go that route unless that's the only way. Thanks.
