Professor Hadley was speaking again. Turning away form his partner slightly, he refocused on the Professor. So why did pizza dough have sugar in it. Simon paused. Hmmm... Maybe.. He raised his hand. "Perhaps the sugar is a nutrient for the yeast? By having the yeast there, it makes the yeast more effective at making the dough rise."

Did that make any sense?

Well, he didn't know.

He thought it did, but oh well. He shrugged nonchalantly. They'd find out the answer soon.
