Spice mixes consist of carefully blended spices or herbs. When a recipe requires a specific combination of herbs or spices, it proves convenient to pre-blend these ingredients. Various pre-made blends, including chili powder, curry powder, herbes de Provence, garlic salt, and seasoned salts, are traditionally offered by grocers. Additionally, baking blends like pumpkin pie spice are commonly available. Home cooks can easily create these spice mixes in advance for later use.
