This Mediterranean spice is a flower bud that has not bloomed. It is pickled and dried to give it a salty and rich taste with a hint of lemon and floral notes. Since it is so rich and salty, it can be replaced with chopped green olives if you have to. Although it is not the same, it does have a meaty and salty taste. Other good substitutes include chopped pickles, green peppercorns, caper berries, or artichoke hearts.
