Using sugar when making pizza dough A lot of the recipes that I've seen on YouTube and different forums have used four main ingredients when making pizza dough - flour, water, yeast, and salt. I'm confused because I though sugar is also a main ingredient since yeast feeds on it. Would y'all recommend always adding sugar to the pizza dough recipe? Also, what if the flour that's being used already has a few grams of sugar - should I still add sugar to the list of ingredients?
There are plenty of fermentable sugars in the flours commonly used in pizza making.  Additional sugar is completely unnecessary.
