Something that’s sapid is very flavorful or savory. A sapid beef stew tastes rich and delicious.
The adjective sapid is a fairly uncommon way to describe something with a rich, deep flavor. You can declare your grandmother’s Thanksgiving feast sapid, though you may have to reassure her that it’s a compliment — sapid is more often used in scientific or industry writing about food than in cooking magazines. It comes from the Latin sapidus, “savory, or having a taste,” from the root sapere, which means both “to taste” and “to be wise.”
