I had pretty much given up trying to make authentic tasting Mexican food at home. After all, I live in a place with numerous good Mexican restaurants, so why bother. The grapes were probably sour anyway.
Then a couple of months ago, I was wandering through the food section of my local Wal-Mart (it pains me to have to write that but its true), and suddenly, I noticed a little plastic tub in the frozen food area labeled Red Chile. The brand name was Bueno. The ingredients in the tub were water and ground roasted red chilies from New Mexico. That was all. I soon realized that there were four different chili products available from Bueno in the store: red chile either mild or hot, and green chile mild or hot. All were frozen.
These are truly amazing ingredients. The flavor is much superior to dried chili powders. Suddenly, I can make pozole, chili sauces, and even authentic tasting caldo de pollo.
I live in southwestern Arizona, and I do not know how widely this product is distributed elsewhere. The company that produces these tubs of frozen chile is a small family owned business. You can go to their web site at www.buenofoods.com and order the products. Unfortunately the shipping costs, because you need next day air, are higher than the cost of the product. But if you crave homemade Mexican food, it still may be worth it.
