Wood fired pizza oven, hot as hell, no tray just the bricks. Cooks in around a minute.
If you cooking it in an oven I would use a stone and have it all as hot as possible. My oven at home goes to around 250 I think, that should do it.
The cast iron pan method works pretty well too if you google it. Probably better than the oven.
Sauce recipe:
1 can chopped tomatoes
1 tsp Olive Oil
1 clove of garlic
1 or 2 basil leaves
1/2 tsp Balsamic
1/2 tsp chilli flakes
1/4 tsp salt
Blend 3/4 of the tomatoes with everything else and then add the remaining tomatoes.
This makes it mostly smooth with just a few 'lumps' of tomato
Heat slowly until it simmers, taste it and see what you think.
Add some water if you think it's too thick.
That's all there is to it.
