A tomato is not just a tomato - but as the basis of the tomato sauce, it's an essential part of a classic pizza.
½ red onion
2 cloves garlic
1 fresh tomato
1 can peeled tomatoes
½ handful fresh basil with stalks
4 stalks thyme, preferably fresh, but dried can also be used.
1 small can tomato puree
2 tsp olive oil
salt and peper
Mix all ingredients using a hand-held or ordinary blender. The oil is there to bind the tomato sauce, to prevent it from seeping into the base during baking.
If you are using dried herbs, add them after blending the sauce or they will colour it grey.
Season with salt and pepper.
