Mix water with yeast, let it sit for a minute or so. Add sugar and salt. In small portions add flour. If you are using mixer, use dough hook, mix on low speed until the dough comes together in a mass. Mix on medium speed for 2 minutes. Dough should clear the sides but stick to the bottom. (If it is too sticky, add 1 tablespoon of flour at a time. If too dry, add 1 tablespoon of water to dough to adjust.) Let dough rest for 5 minutes.
