To prepare the products. Measure sour cream and flour with a glass of sour cream. Flour may need a little more, you will see the batch.
In a bowl, mix all the ingredients on the dough. It should be consistency is not liquid, but not dense, sticky.
Baking sheet grease with vegetable oil or lay with baking paper or silicone Mat, put the dough and a wet hand or spoon, which should be periodically moistened with water, literally smear the dough on the surface. I made a double norm and I got one pizza on a round pizza pan and one on a classic baking sheet from the oven.
And then classics. Grease the surface with tomato paste or ketchup.
Spread out the ham, sliced mushrooms on plates and everything you love. The set of products of conditional. I put more onions, cut into thin rings, red pepper, sprinkled with Provencal herbs.
Lay rings on top of tomatoes, sprinkle with grated cheese.
Bake in a preheated oven at 180 degrees for about 15 minutes. Here and ready.
Second pizza I did with canned tuna, leek, tomatoes and cheese. Bon appetit!
