just wondering the public opinion on whether the toppings should go on top of the cheese or under the cheese thanks
Your question is too general to answer properly. It all depends upon the style of pizza you are baking.
For thin crust tomato pies where I want a crisper crust, cheese first, and splashes of sauce on top. I try not to bake it to the point where the cheese bubbles and totally combines with the sauce. I prefer the splotches of sauce to remain intact.
For medium crust NY style pies, its sauce first and cheese on top. I bake it until the cheese bubbles, and rises and it all combines together.
For toppings such as Sausage & Mushrooms, I bake the pie until the cheese begins to bubble & rise, then I add the S&M and finish the bake. I do this because I prefer the S&M toppings stay on top and not become submerged in the melted cheese.
