Pay de limón is a very common dessert in Mexico. It reminds me of a 1950´s style cake that my Grandma Frances would have made. She loved making recipes with “secret” ingredients and using all sorts of canned products to cook, as did many home cooks at the time. Basically, all of the ingredients for this recipe can be bought at your local corner store, except maybe the limes. In the States these types of pies or cakes are referred to as icebox cakes and became popular during World War I because they were easy and cheap to prepare, required almost no fresh ingredients and no baking!
