To make the dough, mix the salt, sugar and yeast together in a small jug. Add 70ml of the warm water and stir to combine. Leave for 5 minutes for the yeast to activate. Sift the flour into a mixing bowl. Using the electric mixer, gradually add the yeast mixture along with the olive oil. Continue to combine until a dough has formed which is smooth and elastic. Transfer to a greased bowl, cover with cling film and leave to rise until it is double in size (approximately 45 minutes). Knock back the dough and divide into two. Using your hands, shape the dough into two round discs about 25cm in diameter. Place the pizza bases onto two baking trays lined with nonstick baking paper. Pre-heat the oven to 220°C/ 425°F/ Gas mark 7. Add your desired toppings and bake for about 15 minutes or until golden and brown. Serve immediately.
