Dissolve yeast in the warm water in (this takes about 5 minutes).
Stir together the sugar, sea salt and flour in the mixing bowl.
Add the dissolved yeast/water, the olive oil and the rosemary.
Stir and attach a dough hook to the mixer and knead the dough on low to medium speed , until the dough is smooth and elastic. This process will take about 10 minutes. If you don't have a mixer, you can mix the dough in a bowl and turn it out onto a floured surface and knead the dough by hand adding a little more flour if necessary.
Turn off the mixer. Add a little extra olive oil to the top and sides of the dough and put a little oil around the inside of the bowl. Cover the bowl with plastic wrap and allow the dough to sit for two hours. It will double in size.
Remove the dough from the bowl. Tear apart three pieces of the dough.
Place the ball of dough on a floured surface and roll out the pizza dough using a rolling pin.
Top with sauce and your favorite toppings.
Bake in a 350 degree F oven for about 15 minutes or until the cheeses melt and the edges are lightly browned.
This dough recipe will make 3 10-inch pizzas.
