Put the beans in the bottom of a bowl, and put the rice over the beans. Then shake the bowl back and forth gently. You will notice the dried pinto beans rise to the top. This is also a quick and easy way to get the last few nuts out of the detritus and crushed nuts in a nearly empty can of mixed nuts!
