How to avoid getting the pizza all watery

pizza

When I cook pizza it gets all watery. There's literarily water formed on top of the dough. I believe it's released by the mozzarella, but I'm not totally sure.
Any ideas how to avoid this?

Some more information: I'm cooking at around 230C (according to the oven, who knows!) with an electric oven. No stone, just the metal tray. The pizza has exactly the same shape as the metal tray (which is a rectangle, just as the oven).

According to my last experiments, the source of the water is definitely the cheese. I'm cooking the dough, then adding the tomato sauce, then adding the cheese and the water doesn't appear until the cheese-phase. I tried all the possible mozzarellas that I can get at the supermarket with the same result.

There are a number of factors that can contribute to a watery pizza:

  • Cheese If you think the cheese is the culprit, you can try using a "low moisture" mozzarella (these are dry to the touch on the outside). If you are using a "fresh" mozzarella (these usually are sold in a brine), e.g., classic mozzarella di bufala or mozzarella fior di latte, I recommend slicing the cheese as opposed to grating the cheese. The idea is that slicing the cheese will produce less surface area, and thereby reduce the amount of water that leeches out. Also, I recommend dabbing the cheese slices with a kitchen towel to remove any surface moisture. If you use this method, it will also help to cut the cheese in very thin slices, since that will release more moisture before it touches the pizza and it will also reduce the amount of cooking time.
  • Tomato Sauce I recommend making the sauce yourself. As opposed to simmering the tomatoes/sauce on the stove for a long time, I prefer making a light tomato sauce that actually cooks on the pizza itself. I quickly purée the tomatoes (canned are fine) in a food processor and then let them strain in a fine mesh colander for 30 to 45 minutes, stirring occasionally. That gets rid of a lot of water (the tomatoes lose about half of their volume). Throw in some minced garlic, chopped basil, and season and it is ready to go on the pizza.
  • The Cooking Method Since my home oven doesn't get as hot as a traditional pizza oven, I always "blind" cook my pizza without the cheese. In other words, I throw the dough, add the sauce, and then cook it with just the sauce for 4 or 5 minutes. This allows any extra moisture in the sauce to cook off. I then remove the pizza, add the cheese, and then broil it until the cheese is melted and browned.
  • The Dough If the dough ends up becoming soggy, you can always compensate by making it a bit thicker.
