Spices can be used in various forms, including fresh, whole, dried, grated, chopped, crushed, ground, or extracted into a tincture. These processes may occur before the spice is sold, during meal preparation in the kitchen, or even at the table when serving a dish, such as grinding peppercorns as a condiment. Certain spices, like turmeric, are rarely available fresh or whole and are typically purchased in ground form. Small seeds, such as fennel and mustard, can be used either in their whole form or as a powder, depending on the culinary need.
