I disagree.

Grapes are not wine until crushed and fermented (simplified I know) Cement is not concrete until it dries. Cake batter is not a cake until it’s baked.

None of the initial three items above are their latter item. You do not treat any three of them the same. You do not walk on wet cement. You do not ice and decorate raw cake batter (least most people do not attempt to as the result would be messy) and you literally only have grape juice if you crush grapes, no getting drunk over some smooshed fruits.

In ALL of these there is literal chemical change involved to create a new compound. AKA You can not go back, it is NOT the same item as before.

So the pizza item here is not pizza. Because the dough has yet react to the heat and ‘compound’ into the crust we all know and love(or hate).

So I disagree with YOUR logic of an uncooked pizza is not yet chemically “a pizza.”

I emphasis “your” because Someone above called a tortilla with pizza toppings a pizza, and then that just becomes what I perceive to be an argument of linguistics/etymology . All your egg example is an etymology issue. We just don’t have a word for cooked egg like we do other meats or goodies.

Edited for grammar and spelling. Probably still shitty.
