For the dough, cook Jerusalem artichoke or similar vegetables until soft and puree. Then stir the pureed vegetables together with the chickpea flour, coconut flour, wheat flour, baking powder, salt and water to form a thick mass. Lay out baking paper on a baking sheet and distribute the mixture evenly over it.
Then prebake the dough in a preheated oven for about 10 minutes at 200 degrees convection until lightly golden brown.
Carefully turn the pre-baked dough over on the baking paper, so the pizza will later be more evenly crispy on both sides. Now spread the tomato sauce on the pizza base. Then top with cheese and any other ingredients of your choice.
My tip: goat cheese, spring onions and thinly sliced Jerusalem artichoke or sweet potatoes.
Then bake the pizza for another 15 minutes at 200 degrees. As soon as the cheese turns lightly brown, the pizza is ready.
