Curry is often associated with Indian food - and curry powder is thought of as its key ingredient. This is a misconception, though, because authentic Indian food does not contain curry powder.
In India, the word "curry" means gravy or sauce. Many Indian dishes call for powdered spice mix in the sauce, often a blend of spices known as garam masala, mixed with coriander powder and turmeric.
In India, Indians would be confused if you mentioned curry powder, as curry mixes can include so many different things. Curry, with many different flavors, can be Bangladeshi, Indian, Sri Lankan, Indonesian, Malaysian, Pakistani, Thai or from any other South Asian cuisine, and it has been adopted into all the mainstream cuisines of the Asia-Pacific region.
Curry has become an international dish recognized the world over, usually served as a stewlike dish with many spices and seasonings. It can be flavored with hot, sweet and sour tastes depending on the region from which it hails.
Curry may or may not be made with curry powder. The curry powder available in the supermarket is not a single spice but a blend of spices, including black pepper, chili powder, cloves, coriander seeds, fenugreek, cinnamon, cardamom, cumin, ginger, turmeric and nutmeg. You can buy ready-mixed curry powder in the spice aisle of your grocery store or make your own at home.
Different types of curry use different main ingredients, depending on the region of India. Curry from the Punjab region, for instance, is heavy on the butter and cream. Curry from Southern India usually has coconut and coconut milk as well as curry leaves. To make things more confusing, curry powder may contain curry leaves, which come from the curry tree (or curry leaf tree), which is native to India. So, it is actually impossible to have a uniform curry powder to be added to anything to make a curry.
The real Indian curry is a wonder of coordination and expertise, and it uses the precise spices that make a balanced dish. It is not cooked heavily with a flavor of chilis, as most western curry fans like to believe. Each single spice that goes into making the curry powder has a specific role in aiding digestion and helping in absorption of just the right nutrients from the food.
When a curry is being cooked, one has to start with the base sauce, then add the curry powder, the stock or water and the vegetables or meats, then simmer on low heat for that perfect taste. In fact, one would find the famous curry powder in very few Indian kitchens.
