Chef Ravago shares his tips with Epicurious:To seed dried chiles, use a sharp paring knife to make a slit down the side and carefully scrape out the seeds. It's a good idea to wear gloves when handling chiles. According to Ravago, you can vary the number of each chile you use, so long as the total number equals 22, but only use pasilla, mulato, or ancho chiles. Do not substitute another type. Making mole is a time-consuming process, but Chef Ravago warns against taking shortcuts; otherwise, the mole will have an off taste. For instance, the recipe calls for toasting each type of seed individually. This is done to intensify and lock in the flavor of each, as the heating process brings the oils to the surface. If you heat all types of seeds together, the flavors will become mixed, resulting in a muddy-tasting mole. To make the most of your efforts, prepare a double batch of mole, serving a portion and keeping the rest to freeze. According to Ravago, the mole will keep frozen for up to a month. Simply thaw and reheat. If the texture is grainy after reheating, simply reblend the sauce. For easier serving, chunks of boneless, skinless chicken can be used. The recipe calls for parboiling, but you can prepare the chicken in any number of ways, Ravago says, either baked, roasted, or grilled. You can even use a purchased rotisserie chicken. Or, Ravago says, you can substitute duck, quail, turkey, or any kind of poultry for the chicken.
