I see it as someone who believes for whatever reason (their education, their training, their genes) thinks that their tastebuds are superior to other people’s. These people often can’t see any joy or value in inexpensive food, or food that is liked by a lot of people, or food that has simple ingredients (or the opposite, have lots of un-natural ingredients). God forbid that anyone should actually enjoy something from Taco bell, or the fair, or a plate of nachos at the ball game. These food snobs usually balk at anything less than constant white glove attention and won’t hesitate to belittle the wait staff or snap their fingers to get attention.
Most of the judges on Chopped strike me as being food snobs. They seem to actually disdain food. They give the contestants (who are obviously good cooks, usually chefs or very experienced home cooks, or caterers or cookbook writers) ridiculous ingredients, that real chefs either would never put together (at least not without trying out the recipe multiple times before perfecting it and presenting it to their guests) like Captain Crunch cereal and raw squid and ranch dressing, then they screech at the chefs as if they must be idiots for presenting them with such a terrible tasting dish. .
On the other hand, Guy Fieri, is the opposite of a food snob. He likes lots of stuff, even weird stuff, even old-fashioned American greasy spoon cuisine and he doesn’t expect white tablecloths and doesn’t participate in cork-sniffing or sending back a steak because it was rare and not medium rare (which is a matter of opinion, not exact science). He also likes Spam sushi and stuff he (and I) have never heard of before. And he praises people for good food, rather than screeching at them and telling them how awful they are.
If a young person was going to culinary school, I’d hate for them to get saddled with teachers like the judges on Chopped. It would be very demoralizing.
The taste of food is very subjective. Some people like lots of things, some people only like a limited amount of things, some people can learn to love new things if they try them enough times, others will never venture out of their comfort zone or cultural zone, some people like spicy food, others don’t. But the point is, the taste and perception of food is subjective, not right or wrong.
That’s why I never refer to myself as a foodie, that word conjers up food snobbery in my mind. I prefer the term food enthusiast.
