In college I discovered the absolute greatness that is dipping tortilla chips straight into sour cream. No mixing with salsa required, although, that’s pretty great, too, and still a favorite standby lunch. The first few times I ate my chips into cream concoction, it felt a little wrong, like I was breaking some sort of rule and, even still, decades past living in a dorm, I sometimes catch myself feeling unnecessarily guilty about my unusual snack. Not enough to stop me, of course, but I do sometimes give pause.
