I recently got this book at a used-book store, so I'm just getting to know it. The book covers a broad range of cuisines, both from immigrant nationalities as well as less-widely-known regional cooking. Recipes are sorted into ingredient types (except for breakfast, soup, and dessert), not by country-of-origin. Just like the roast beef, olive oil, tacos, stir-fries, and strudel from long-ago immigrants, the foods of more recent immigrants (mango lassi, pho, fatoush) are becoming regarded as American. It's going to be fun to learn to make these dishes that previously I've mostly had at restaurants.
