Pizza is not made on a grill or with cornmeal on the bottom, it's made on a hot stone, with flour on the bottom of the dough to keep it from sticking. It also does not ever touch pineapples or ranch dipping sauce. What in the actual fuck is wrong with people?
I won't question the cooking on stone part, but as far as toppings on pizza go I honestly don't care. Everyone has different tastes and if someone wants to put whatever abomination on their pizza so be it.
Also I actually like pineapple on pizza, but it's not my favorite. I don't know why people get so offended by it
What about orange juice on cereal? I was skeptical, but a bit of web searching turns up some small percentage of the population actually chooses that life.
That is all true with authentic pizza but as long as I know what I'm getting all of those things (except the ranch are fine with me. If I'm going to a high end pizza restraunt I expect it to be made with flour instead of cornmeal and preferably wood fired but for a home cooked meal I love the cornmeal on shitty store bought dough. Maybe that's just me though, I had it my whole childhood that way.
Why would you gatekeep what's on a pizza? There's a whole range of textures and flavors that work, that you're telling people they can't experience because you're a hardcore traditionalist? Let good food be good food.
