Strange enchilada sauce
I just had a "breakfast enchilada" (not burritto, it had a corn tortilla with ham, eggs, peppers) with a very strange sauce. It was a regular but thinner red chile sauce, but tasted like it had vinegar in it.
Has anyone ever heard of vinegar as an ingredient in Mexican food? Of course, I had this dish today on NYC, and NYC is not known for Mexican food. Maybe some wierd yuppie chef.
