Cool Facts
Mixing and stretching. Kneading mixes all your ingredients together and stretches the dough over and over, which is hard work but super important for great bread.
Building gluten networks. When you knead, you're creating long chains of gluten protein that make the dough strong and springy, kind of like invisible elastic bands holding everything together.
Trapping tiny air bubbles. Kneading pushes air into the dough, and those little air pockets get bigger when the bread rises and bakes, making it light and fluffy instead of dense.
Speeds up baking. Properly kneaded dough rises faster than dough that hasn't been worked, so you can have fresh bread sooner.
Makes dough strong. Before kneading, dough is soft and sticky, but after kneading it becomes elastic and bouncy, able to hold all those air bubbles tight.
