Your nose knows things your eyes can’t see. A good, fresh dough should smell like yeast and flour—think baker’s shop, not garbage truck. If you get a whiff of something sour, funky, or like old gym socks? That’s a red flag.
Don’t be shy—really get in there. Give that dough a good sniff right after you unwrap it. Trust me, your nose won’t lie to you, even if your pizza cravings try to.
