Traditional recipes for mole poblano call for several varieties of dried chilies, which, outside the southwest, are available only at specialty foods stores or by mail order, as well as sesame seeds and/or pumpkin seeds and/or peanuts; roasted tomatoes, and chocolate, among other things. A mole can sound Like a peculiar combination of ingredients, but at its best it is every bit as subtle and well balanced as the most evolved French sauce. Our quick version uses only ingredients available at the supermarket, and broiled, not fried, chicken, which makes the dish easier to prepare, lighter, and most important, still delicious — if not exactly authentic.
