I grew up in the midwest. We survived on processed ingredients. I now live in the Bay Area.
I tell my partner that I need the shitty Kraft cheese for my grilled cheese sandwich, not the cheeses from Whole Foods or Trader Joes, because that's what I had growing up. I need the shitty ingredients for certain specific foods because I want that taste. It's not a lot of meals, but a handful must match my childhood.
