In a small mixing bowl mix the water, sugar and yeast together and wait for about 15mins until the yeast bubbles and activate.
In a large mixing bowl, combine the salt and flour, then combine the 'yeast' solution to your flour (wet into dry) and mix and knead until the dough is smooth and elastic.
Set aside and cover with a moist tea towel, set aside somewhere nice, warm and moist to let it proof to double its size. This may take and hour or so.
When complete, take it out, knock it down and dust a clean working surface. Divide your dough into 2 large pizzas, and roll in into thin bases.
Let your rolled pizza bases re-proof another 15minutes before you add you napolitana sauce, followed by all your toppings.
Pre-heat your oven to 210 deg C, place your pizza to cook for about 10-15 minutes or until dough and toppings are cooked.
Serve while hot!
