Every New Mexican cook has a green chile sauce, but it has to be very good sauce, or her reputation as a good cook suffers. They serve this sauce at any meal. At breakfast it is served over eggs or potatoes. It is used over burritos, in enchiladas, or over grilled meats and roasted potatoes for lunch or dinner. It is best when it is fresh or used within one day of being made. This recipe comes from Sandy Szwarc's "Real New Mexico Chile".
