In the culinary arts, a spice is any seed, fruit, root, bark, or other plant substance in a form primarily used for flavoring or coloring food. Spices are distinguished from herbs, which are the leaves, flowers, or stems of plants used for flavoring or as a garnish. Spices and seasoning do not mean the same thing, but spices fall under the seasoning category with herbs. Spices are sometimes used in medicine, religious rituals, cosmetics, or perfume production. They are usually classified into spices, spice seeds, and herbal categories. For example, vanilla is commonly used as an ingredient in fragrance manufacturing. Plant-based sweeteners such as sugar are not considered spices.

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. A whole dried spice has the longest shelf life, so it can be purchased and stored in larger amounts, making it cheaper on a per-serving basis. A fresh spice, such as ginger, is usually more flavourful than its dried form, but fresh spices are more expensive and have a much shorter shelf life.
