In a small bowl whisk the water, sugar and yeast together. Let it sit for about 10 minutes. If the yeast is good, it will start to froth up.
In the bowl of your mixer, add the flour and salt, olive oil and yeast mixture. Mix everything together using the dough hook for about 5 minutes or until the dough is soft and elastic. When it's done it will come clean from the side of the bowl.
Shape the dough into a ball and place in an oiled bowl, rubbing oil on the dough as well, cover with plastic wrap and refrigerate. If you're not using the dough right away, you can also freeze the dough.
