How to Knead Dough

Kneading is the rhythmic pushing, folding and turning of dough that organizes its proteins into a strong, stretchy gluten network. By hand it takes about 8 to 12 minutes; the dough is ready when it's smooth, elastic and stretches into a thin, translucent sheet without tearing.

What kneading does

Wheat flour contains two proteins, glutenin and gliadin. When they meet water, they bond to form gluten. At first those bonds are random and tangled, like a pile of loose string. That's why fresh dough is shaggy, lumpy and tears easily.

Kneading stretches the proteins out and lines them up into long, overlapping sheets. Each push lengthens them; each fold layers them. Glutenin brings elasticity (spring back) and gliadin brings extensibility (stretch). Kneading also works tiny air bubbles into the dough, which become nucleation sites for the carbon dioxide yeast produces later.

The result is a network that's strong enough to trap gas during proofing and baking, but stretchy enough to expand. That's what gives bread its rise, its chew and an open crumb. Learn more about the process in gluten development.

Let the flour do some work first

Before you knead, mix flour and water and let them rest for 10 to 20 minutes. During this pause, called an autolyse if you leave out the salt and yeast, the flour hydrates fully and natural enzymes start loosening the proteins. Gluten begins forming on its own. You'll notice the dough is much smoother when you return, and you'll cut a few minutes of kneading.

Steps

1. Mix the flour, water, yeast and salt into a shaggy dough and let it rest 10 to 20 minutes.
2. Turn the dough onto a lightly floured or lightly oiled surface.
3. Push the dough away from you with the heel of your hand, stretching it.
4. Fold the stretched part back over the top of the dough.
5. Give the dough a quarter turn and repeat the push, fold and turn in a steady rhythm.
6. Knead for 8 to 12 minutes, scraping the surface clean as needed, until the dough is smooth and springs back when poked.
7. Check with the windowpane test, stretching a small piece thin enough to see light through.
8. Shape the dough into a ball and place it in a lightly oiled bowl to rise.

How to tell when dough is kneaded enough

The look. It changes from rough and matte to smooth and slightly glossy.

The poke test. Press a floured finger 1 cm (1/2 in) in. Well-kneaded dough springs back most of the way within a few seconds.

The windowpane test. Pinch off a golf ball-sized piece. Gently stretch it between your fingers, rotating as you go. If it thins into a translucent membrane you can see light through before tearing, the gluten is well developed. If it tears into a ragged hole early, knead for 2 more minutes and test again.

The temperature. Most yeast doughs do best at 24 to 26 °C / 75 to 78 °F after kneading. A quick probe tells you whether your dough needs a warm or cool spot to rise.

Enriched doughs with lots of butter, sugar or eggs, such as brioche, take longer to pass the windowpane test because fat coats the proteins and slows bonding.

Kneading with a stand mixer

Use the dough hook on low to medium-low speed (speed 2 on most KitchenAid mixers). Knead for 5 to 8 minutes, until the dough clears the sides of the bowl and gathers on the hook. Stop once or twice to scrape the hook.

Watch the dough temperature. Friction from the motor and hook can raise it several degrees. Above about 27 °C / 80 °F, fermentation speeds up and the dough can turn sticky. Use cool water in warm kitchens.

Hand kneading tips

• Use the heel, not your fingers. Fingertips poke holes; the heel of your hand stretches.
• Keep it moving. A steady rhythm of about one push-fold-turn per second works well.
• Flour lightly or not at all. Each handful of extra flour lowers the dough hydration and gives you a drier, denser loaf. Wetter doughs (above about 70 percent hydration) are often better handled with a bench scraper and the slap-and-fold method, where you lift the dough, slap it down and fold it over itself.
• Rest if it fights you. If the dough snaps back and won't stretch, cover it for 5 minutes. The gluten relaxes and kneading gets easier.

Common mistakes and fixes

Adding flour every time it sticks. Early stickiness is normal. Give it 3 to 4 minutes of kneading before you decide it's too wet.

Stopping too early. Most home bakers stop at the "looks mixed" stage. Use the windowpane test, not the clock.

Using too much speed in a mixer. High speed overheats and over-oxidizes dough, bleaching its flavour and eventually tearing the gluten. Stay on low.

Forgetting the salt. Salt tightens the gluten network and controls yeast. Without it, dough is slack and sticky and rises too fast.

Using low-protein flour. All-purpose flour works for most loaves, but bread flour (about 12 to 14 percent protein) builds stronger gluten for chewy, tall breads.
