Everyone has their blind spots -- things that seemingly everyone else in the world already knew, but that they themselves were ignorant of. Over the last week, I filled in one of mine: the Corn Chip Issue. It's a really simple one with a very obvious solution: never buy off-the-shelf corn chips. Fritos, Doritos, and Tostitos are but a pale, flavorless imitation of something you can prepare at home for a small fraction of the money. Somehow, I never realized that all that you need to make tasty, crispy chips that rival the ones you get as appetizers at Mexican restaurants is a 99 cent bag of tortillas from the supermarket and a pot of hot oil. Slice the tortillas into wedges, drop them in hot oil for a couple of minutes, drain them on paper towels and salt lightly. Serve with salsa. That's all it takes. Really, it couldn't be simpler. Somehow I made it through decades without anyone telling me. In case your friends have likewise left you in the dark, I'm blogging it.
