I worked in a pizzeria when I was a kid and have made pizzas at home all my life. There's not many I like better than mine frankly, and although time consuming they're pretty easy.
Preheat the oven to 550F. You'll cook at 450F but you don't want the element to come on and this seems to help a bit.
I tend to tone it down a bit these days as my kids prefer just plain crushed tomatoes as sauce (which is what the local pizzeria does, and frankly it's surprisingly good). But if it's just for me I'll saute an onion, tons of garlic, a jalapeno all chopped fine then add a can of crushed tomatoes and a can of tomato paste then spice it up. I usually make enough to last about 8 pizzas and keep it in the fridge in a glass bottle.
The lazy mans way is to open a can of crushed tomatoes, add basil and oregano, mix, use.
Roll the dough out. Flour the work surface and get the rolling pin out. Press the dough down with your fingers first, keep turning if over and roll roll roll till it'll fit the pizza pan you have. You really want to be rolling from the middle to the edge, not the whole thins. Speaking of pizza pans...
The most common mistake is to use too much cheese and not enough sauce. You can do this and it'll work but you end up with a rubbery layer of cheese on top not the nice melding of sauce and cheese. Use a fair bit of sauce and not enough cheese to cover it so you can still see some sauce.
Properly you should finely grate a 1" square piece of parmesan and half that of romano on first.
Assembly One variation at this point if you like things spicy is to very finely chop 4-6 cloves of garlic, one jalapeno and a quarter of an onion and mix them in with the sauce on the dough before you add cheese. Yeah, baby.
Now add 2/3 of the mozzeralla evenly.
Now you add ingrediends. My kids like plain cheese pizza so I put ingredients on half. First pepperoni, sliced fairly thick and for gods sake read the label. If it says chicken or turkey get some other kind. You don't want to overdo it, space them out so there's like a piece of pepperoni then a space for one. Repeat.
Now the mushrooms - sliced fairly thick but not as thick as the presliced ones which do not seem to work well. These shrink a LOT when cooking so you can literally cover the entire surface.
Nex is olives. The cheap ones in jars just don't have enough taste. Get the deli packed giant ones. Don't add to many one every 3" or so is about right.
Next the jalapenos. Some people use bell pepper but I think they're vile. You do need some pepper flavour and 4 jalapenos per extra large pizza, deseeded and sliced very thin is about right. For me.
Now slice a small onion thinly and put pieces of it everywhere.
Now you can put the remaining 1/3 of the grated mozzeralla on.
Stick it in the over and turn it down to 450. You do this so the element doesn't come on as much. You CAN cook it at 500, it's better for you (there was an article about this recenlty but I'm too lazy to look it up). But it's dicey. The crust will get done too quickly and the cheese may not all melt properly. It's worth a try though, the article was pretty compelling. Jus don't cook it at 550. That won't work. Ask me how I know. (Oopsie)
You can't tell if it's done by the top you have to look at the crust. Golden brown is perfect. Brown is oevrcooked and will be too crunchy. If it's golden brown it should be soft and chewy. You really don't care what the top looks like you're going by the crust. Underdone (slightly) is better than overdone. You want it just on this side of golden brown. ABout 13-15 minutes for a large pizza.
When it's done take it out, shake it off the pan. Iinvert the holy pan and let it cool on that. You want it very warm but not too hot to eat. Or let it cool on a baking rack or wooden surface or something that lets air get underneath. For the real pizza parlour taste use a pizza box. The cardboard gives off something that does gove it a pizza parlour flavour you don't get otherwise. Dioxin probbaly...
After a few minutes it's cool enough to cut with a proper pizza cutter or a cleaver. Cutting it with a knife or scissors is messy.
It may take a few pracice runs but once you get the hang of it you'd be hard pressed to want pizzeria pizza again. Plus it's stupid cheap by comparison.
