In the 50s my mother, from Minnesota of English-German stock, for some reason was pretty adventurous in the food department. As a result I am accustomed to much broader variety of foods than most people I know, and it shows in my cooking -- when we have a pot-luck at work, few are interested in what I bring, although the few like it; others shy away. (And not always because the chiles are too hot.) She got interested in Mexican food when that wasn't "ethnic", but simply considered low class. Pal with cheese. The family would go to Olvera St for the real authentic stuff, and she would go from her middle class LA neighborhood (father was UCLA prof) to real Mexican markets in search of the ingredients mentioned in her simply published Mexican cookbook, that she got at a cooking class. That was not long after the zoot suit riots in East LA, before Mexican food had entered the Anglo mainstream. So I got to like the taste(s) of Mexican food, and over the years would encounter some that was relatively hotter, and I didn't mind. When I was in college, a favorite place was Zacatecas Cafe in Riverside CA, where the plates, fresh from heating in the oven, like the slab in a hot rolling mill, would bubble on the counter in front of you for a while before cooling enough to be eaten. The salsa was relatively hot. So I guess my taste for heat was acquired gradually -- started with Olvera St food of the 50s that was authentic but not hot, and gradually expanded to other flavors and more heat. And thanks to my mother for exposing me to so many different foods. Jim
