Curry! - Real curry powder is fresh, vibrant, and complex, but the long list of spices which can be used in this mixture lose their potency quickly. It's best to either grind whole spices before using or keep the mixture in an air-tight container for no more than a couple months. The spices that you almost always find in this Indian mixture include cumin, coriander, turmeric, pepper, and chiles, but the list can go on to include 20 or more ingredients. Mix your own or make sure to taste your curry powder to see what the exact flavor profile is and just how hot it might be before adding.
