Step 1

Add the yeast to the lukewarm water with 1/2 tsp sugar for 2 minutes. Combine the flour and salt in a large mixing bowl. Make a well in the centre and add the water/yeast mixture whilst mixing the dough together with your hands or a metal spoon until you have obtained a dough. If it's too sticky you can gradually add a little more flour.

Step 2

Dust a clean work surface with a little flour and knead the dough for around 10 minutes until it's silky smooth and soft. If you lightly press your finger on the ball of dough it should spring back up easily. Add 1 tbsp of olive oil to a large clean bowl and rub all over until the bowl is coated. Shape the dough into a ball and place in the bowl, rub the top of the dough with a tiny amount of olive oil. Cover with cling film and leave in a warm place for at least 3 hours until doubled in size.

Step 3

When you are ready to make the pizzas pre-heat the oven to 225°C.

Step 4

Divide the dough in half roughly with your hands. Lightly dust a work surface with flour and begin to roll out your first half of dough. The pizzas can be made round or rectangle depending on your baking trays. Roll out the dough as thin as possible without tearing around 30cm in diameter. Lightly dust the baking/pizza trays with semolina then place the dough on the tray, repeat with the second half of dough on a separate tray.

Step 5

For the topping add the grated cheese, sour cream and crushed/grated garlic to a bowl and season with salt and pepper. Mix everything together until thoroughly combined. Divide the mixture between the two pizza bases and spread out evenly. Top each pizza with layers of speck and then finely sliced mushroom. Bake in the oven for around 10 minutes until the base is crisp and cheese bubbling and melting.
