In honor of Cinco de Mayo I thought it appropriate to share a "Spanish" recipe. As you look at old community cookbooks they often have various versions of "ethnic" recipes. Of course it appears that typically there is one ingredient in the recipe that for some reason makes it ethnic. In the recipes I find that are "Spanish" it's usually the inclusion of onion and/or tomato sauce.
In this recipe from The Women's Society of the First Presbyterian Church in Winfield, Kansas Cook Book one of the many "Spanish" recipes is for Spanish Pork Chops.
This early 1930s cookbook actually has a bunch of "Spanish and/or Mexican" recipes like Mexican Tomato Sauce, Spanish Meat Balls, Tamale Pie and Spanish Beans.
But if you really want some Mexican recipes for Cinco de Mayo you may want to check out something from an "authentic" Mexican cookbook like El Concinero Espanol by Encarnacion Pinedo (1898) or the El Paso Cook Book by the Ladies' Auxiliary of the Y.M.C.A. (1898).
