Pizza with prosciutto and rocket

Method

• step 1

  Mix the yeast with 250ml warm water and the sugar and leave to sit for 10 minutes. Put half the flour into a mixing bowl and pour in the yeasty liquid. Stir with a spoon until combined then leave somewhere warm for 10 more minutes, until tiny bubbles form on top of the mixture.

• step 2

  Meanwhile, start the tomato sauce. Fry the onion and garlic in 4 tbsp olive oil until softened. Add the tomatoes and bring to the boil, reduce the heat to a simmer and cook for 20 minutes, stirring occasionally until thickened.

• step 3

  To finish the dough add the rest of the flour, 1 tbsp olive oil and 1 tsp salt and bring together to form a soft dough. Then knead for 5 minutes. Put in an oiled bowl, cover with clingfilm and leave somewhere warm for 30 minutes or until the dough has doubled in size.

• step 4

  Slap the dough down and knead for 3 minutes, until soft but not too elastic. Divide into 2 pieces and roll each into a ball, then leave these to rest on an oiled baking sheet covered with oiled clingfilm for 10 minutes.

• step 5

  Heat the oven to its highest setting and put in 2 heavy baking sheets to heat up. Flatten each ball of dough and roll out with a well-floured rolling pin as thinly as possible.

• step 6

  Put a pizza base on each hot baking tray and top with some tomato sauce and mozzarella. Cook for 8-10 minutes, or until the base is crisp. Take out of the oven and top with the prosciutto and rocket.
