There are many ways to use whole dried chiles: Add to sauces, soups, and stews. Rehydrate by soaking in warm water for about 20 minutes (but not longer or they can become bitter), then chop as desired. Toast the chiles in a dry pan for added depth of flavor before grinding.
All chilis found around the world today have their origins in Mexico, Central America, and South America. They were spread by Spanish and Portuguese colonists, missionaries, and traders, together with many other now common crops such as maize, tomatoes and pineapples. This is now called the Columbian Exchange. The chili varieties found in Southeast Asia today were brought there in the 16th or 17th century.
