In a small measuring cup add warm water, yeast, and sugar. Gently stir and set aside for 10 minutes. This will activate the yeast and you will see and you will see a foam form on top.
In the bowl of your stand mixer, add in the flour and the salt, mix together. After yeast has activated add the yeast mixture into the flour and the melted butter.
Using your dough hook mix on a low speed until dough is formed. You want to dough to form one cohesive ball that is not sticky and manageable to touch, and no flour/dough sticking to the sides or bottom. If dough is too wet add a tablespoon of flour at a time until dough is no longer wet. If dough is too dry add small amounts of water. Once dough is formed continue kneading for another 7 minutes.
Remove dough from bowl and add about 1/2 tbsp of oil (olive/vegetable) to grease the bowl. Once greased add dough back in the bowl. Flip dough over a few times to grease to top of the ball. Cover with plastic wrap and a kitchen towel and place somewhere warm to rise. Let rise for an hour or until dough has doubled in size.
