By gently simmering vegetables and meats, you preserve each ingredient's distinct, pure flavor. You need very little oil or butter for moist-heat cooking, so you produce lean and healthy dishes. Each ingredient also becomes extra tender -- simmering lends delicacy to meats and vegetables and retains their subtle flavors. The French say that a simmer makes the pot smile; these simmered meals will elicit smiles from everyone at the dinner table.
