For tomato sauce, heat olive oil in sauté pan together with garlic cloves, making sure that garlic doesn't burn. Add tomatoes and break them up with wooden spoon. Add salt to taste, then cook on medium heat for about 10 minutes, stirring often, until most of the thin liquid is evaporated. Cool before using.
For the dough, place flour in a bowl. Make a well in the centre.
In separate cup, dissolve the yeast in 1/4 cup water (taken from 1 1/2 cups). When ready, add it to the flour. Mix, then add another 3/4 cup of water, salt and olive oil. Mix again. Add the last bit of water slowly, mixing, to make a soft ball of dough that is a bit tacky, but not sticking to your fingers - you may not need all of the water.
Place the dough onto clean surface. Knead for about 8-10 minutes, until smooth and soft.
Oil the inside of a bowl and put in the dough. Cover with plastic wrap and let the dough rise in a warm place for 1 1/2 to 2 hours, or until it doubles in size - or let it sit in the fridge overnight to slowly rise which gives it a great flavour, remember to bring it out about 45 min before you want to use it.
Before you are ready to bake the pizza, preheat the oven to 500F.
Divide your dough in half, then half again. Keep the rest covered with plastic wrap while working with one piece. (if not using all of it, wrap tightly and freeze)
Oil baking sheet or, if using baking stone, place baking stone in the oven.
Flour your surface and flatten the dough into a round with your fingers (or roll it out and then flatten with your fingers). If the dough is still too elastic, just rest it for a few minutes and then continue after it relaxes a bit more. Place on prepared oiled baking sheet and finish to stretch it out as thin as you can, leaving a thicker edge all around.
Top with tomato sauce and a sprinkle of olive oil.
Bake pizza for about 15 minutes (check it at 10 minutes time), then take it out and quickly top with mozzarella slices and grated parmigiano. Place back in the oven for additional 5 minutes until the cheese is melted.
Take pizza out of the oven, lay prosciutto slices over it, spread fresh torn basil over the top and give it a final drizzle of olive oil.
