Do you have a recipe for a Mexican dish served in a molcajete.?

The recipe you want is probably original to that restaurant. Try to find former employees and work your way to the kitchen help. The owners may be gone but their employees are probably working at similar restaurants in the area. As a restaurant owner I am continually amazed at who knows who, especially in the kitchen. I don’t know the demographics of you area but with a little luck you will get that recipe.
