Bread basics: understanding dough
What yeast, kneading and proving actually do.
Bread needs only four things: flour, water, salt and yeast. How you handle them makes the difference.
Kneading
Kneading stretches the gluten in the flour into a strong, stretchy net. That net traps the gas the yeast makes, so the bread rises.
Proving
Proving is the rest that lets the yeast work. Warm places make it faster; cool places make it slower but tastier.
