*Soak the chestnuts overnight in cold water (or soak in boiling water for 5 to 10 minutes) to make them easier to peel. Cut off the rounded end with a sharp paring knife, then remove the hard outer shell and the thin inner skin. Wash the peeled chestnuts lightly in cold water to get rid of their starch. To prevent discoloration, keep the chestnuts in a bowl of cold water until it is time to add them to the rice, then drain them and proceed with the recipe.
