Spice mixes are blended spices or herbs. When a certain combination of herbs or spices is called for in a recipe, it is convenient to blend these ingredients beforehand. Blends such as chili powder, curry powder, herbes de Provence, garlic salt, and other seasoned salts are traditionally sold pre-made by grocers, and sometimes baking blends such as pumpkin pie spice are also available. These spice mixes are also easily made by the home cook for later use.
