A holiday "gift" of cookies, etc. got me thinking about this one. My neighbor likes to bake, but consistently uses sub-par ingredients, like margarine in cookies, or generic chocolate chips. Seriously, most of her stuff is pretty inedible. Maybe that makes me a food snob, but it's just not worth eating if it tastes like mud! (Really, she made some cupcakes with "chocolate pudding" in the middle that had absolutely no taste whatsoever). So, I was just curious what some of your pet peeves are?
