I live in Santa Fe, NM. Elevation here is 6500 ft, so I'm always interested in high altitude recipes, especially for baked goods. My DH and I feast on the many types of chile (local spelling) from the area. My favorite general cookbook is The Best Recipe, from Cook's Illustrated. I love to read of their testing adventures, as they track down the best techniques and ingredients. My favorite fun cookbook is The Surreal Gourmet, Real Food For Pretend Chefs, by Bob Blumer. It's small book with hilarious illustrations by the author. And every recipe I've tried has turned out super.
