Sesame seeds are tiny, oil-rich, flat oval seeds with a nutty taste and a delicate, almost invisible crunch. They are highly valued for their oil which is exceptionally resistant to rancidity. Toasted white and black sesame seeds are sprinkled on salads, sesame paste is added to sauces, and delightfully aromatic sesame oil is used to flavor everything from dips to marinades and finish off a stir-fry.
