This is a Georgian spice used in Georgian cuisine, also referred to as Georgian Saffron and formally as kviteli kvavili. It has a sweet flavor and is sold whole (dried) or powdered. Several varieties of tagetes (marigolds) are edible, but the most common one is tagetes patula. This is the same flower woven into Indian garlands to decorate gods and honored guests, but only in Georgia is it used as food. The flavor of tagetes is earthy, spicy, with a hint of green apple and orange.
