While trying to help my dear friend Mommy Diva find some New Mexico style red chile sauce, I came across this recipe. I just have to try it! According to Diana Kennedy[http://en.wikipedia.org/wiki/Diana_Kennedy], Pasilla chilies are a long and skinny variety of chile, while Ancho chilies (dried poblanos) are shorter and wider. However, in certain parts of Mexico, the Ancho chile is called Pasilla, and because of immigration, is commonly known as Pasilla in many parts of the US. See blog here with step by step pictures! http://www.elise.com/recipes/archives/005178mexican_red_chili_sauce.php Prep and cooking time are concurrent Note when working with chilies, either wear protective gloves or wash your hands very thoroughly with soap and warm water after handling the chilies. Do not touch or rub your eyes if you have been handling chili peppers.
