How does yeast make dough rise?
You pinch off a piece of raw dough and it feels dense, cool, slightly sticky. An hour later it's doubled in size, soft and pillowy, full of air. What happened? You didn't add anything. You didn't pump it up. The dough just… grew.
The secret is already inside: tiny living creatures called yeast. Each yeast cell is so small you'd need a microscope to see it, but you sprinkled billions of them into the flour and water when you mixed the dough. Right now they're waking up, surrounded by food.
