Pizza Cognition Theory: postulates that the first pizza a person eats becomes the standard by which that person judges all pizza he or she subsequently eats.
According to Sam Sifton, “The first slice of pizza a child sees and tastes (and somehow appreciates on something more than a childlike, mmmgoood, thanks-mom level), becomes, for him, pizza. He relegates all subsequent slices, if they are different in some manner from that first triangle of dough and cheese and tomato and oil and herbs and spices, to a status that we can characterize as not pizza.”
My earliest memories of eating pizza are mix of two places. The first being Pizza Hut and the second Peter Piper Pizza. I still have a fondness for Peter Piper Pizza. I wouldn’t say either shaped my foundation as to what makes a pizza a pizza though. I’m pretty flexible about what makes a pizza. I do believe there is no defacto best kind of pizza just preferences of them.
