"Making" the pizza with a premade dough and pre-cut toppings is just a 1 minute operation to spread sauce and throw some toppings on it isn't it? Not much bonding there in my eyes...
Sure your homemade pizza improves significantly when you can get your oven very hot and cook it really quick, but homemade pizza from a conventional oven (250C or so), using your own dough and toppings is still miles better than frozen.
I bet you’re fun at parties!
Don't do to France or Italy is my recommendation in all honesty, ignorance is a bliss.
Freezing ingredients doesn't really make them taste super different on a pizza to me. Sure if you buy a cardboard cheap frozen pizza there is not much dough and toppings, but if you take the one that comes close to what you would pay in a restaurant it's not much different in my view.
I also think comparing the quality of cooking of Italy with France is unfair. Italy seems to have a way more basic cooking style.
