Hello everyone. I'm making "Enchiladas Rojas de Aguascalientes" from Diana Kennedy's The Essential Cuisines of Mexico for a dinner party. I've made the recipe before and it was very successful, but this time I'm making it for a group that includes a vegetarian who cannot eat the egg yolk in the sauce. The sauce calls for: 4 Ancho Chiles 1 1/2 cups hot milk salt 1 clove garlic 1 hard-cooked egg yolk 2 tbs Veg. oil I assume that the yolk is in their to enhance the body and mouth-feel of the sauce, and if so, it does a great job. I'm wondering if there are any vegetarian-friendly substitutes that can take its place, or if I can just omit the yolk with minimal effect on the sauce. Thanks in advance for your thoughtful suggestions!
