Kneading pizza dough: by hand, spiral or stand mixer

What kneading really does

Kneading is not just mixing. Three things happen at once:

1. the flour absorbs the water in the recipe;
2. the dough takes in oxygen;
3. the mechanical energy from your hands or the mixer forms and organises the gluten network.

That third point is the one that matters. Gluten comes from flour proteins, water and this energy: without it, there is no structure. See the page on gluten strength and extensibility to understand exactly what you are building.

That energy has a side effect: part of it turns into heat. The faster the machine works, the warmer the dough gets. Mastering kneading means controlling both structure and temperature.

Hand, stand mixer or spiral

Every method can produce an excellent Neapolitan pizza, and kneading by hand is still the best school before moving to a machine. What changes is the amount of energy delivered: it rises from hand kneading to a stand (planetary) mixer, and again to a spiral mixer.

These figures are starting points: every machine has to be calibrated by measuring, always at the same speed.

Speed in rpm

On a spiral mixer, the parameter to watch is rotation speed in revolutions per minute. The energy delivered to the dough is proportional to it.

If your machine tops out at 180–200 rpm, it still works, but it is slower and trickier for wetter doughs. A single-speed mixer is a real handicap at high hydration: kneading can then take 25 to 40 minutes.

One often-overlooked point: a bowl only kneads well when it is two-thirds full at most. A 5-litre bowl is full with 2.5 kg of flour but works best with 1 to 2 kg.

Ingredient order

The order differs between hand and machine, and follows a simple logic: build the mix first, then the network.

In a mixer:

• flour and yeast first (plus the preferment in an indirect dough);
• a first portion of the water on first speed: for a contemporary dough at 68 % hydration, enough to reach 63 %;
• the salt, dissolved in a little water, once that first water is well absorbed;
• switch to second speed and add the remaining water gradually, waiting each time for the previous addition to be absorbed.

By hand you work the other way round: start with the water, dissolve the yeast in it, add a little flour, then the salt, then the rest of the flour gradually.

Salt, without the drama

Salt does four jobs: it seasons, strengthens the gluten, slows down yeast and enzyme activity, and helps the flour absorb water during kneading. You often hear that salt "kills" yeast. Added at the right moment and the right dose (I stay between 2 and 2.5 %), it causes no trouble.

Dough temperature at the end of kneading

This is the first number I check. Between 23 and 25 °C (73–77 °F), with an acceptable range of 22–26 °C (72–79 °F), the gluten network holds best, the dough is less sticky and easier to handle. Throughout kneading I keep the dough around 21–24 °C (70–75 °F) and never above 28 °C (82 °F).

This temperature also sets how fast fermentation starts. The main lever to hit it is the water: the water temperature calculator applies the formula water = 3 × dough target − room − flour − mixer heat. How temperature shapes everything that follows is covered in why temperature drives dough.

When to stop: the windowpane test

Times give you an order of magnitude:

But the dough has the final say. It is ready when it is smooth, elastic and no longer sticky. To check, I do the windowpane test: I stretch a small piece of dough between my fingers. The network should be smooth, elastic and resistant, and the dough should stretch without snapping. If it tears immediately, the gluten is still too weak.

By hand, if the dough gets too sticky along the way, a covered pause of 15 to 30 minutes is often enough to make it workable again.

Autolysis: useful, not mandatory

Autolysis means mixing only the flour and water first, then letting them rest before adding the rest. In a mixer, that means about 4 minutes on first speed with all the flour at 60 % hydration, then a rest of about 45 minutes (30 minutes to 1 hour depending on flour strength), away from draughts. Then you add the yeast and the salt, always separately.

Two things happen during that rest. The flour finishes hydrating and gluten starts to form on its own, without any mechanical work. At the same time, the flour’s enzymes loosen part of that network: the dough becomes more extensible, less elastic and less sticky.

Its main benefit: the kneading that follows is shorter. It is a valuable trick with a single-speed mixer and a good option for a direct dough. You do not need it to make a great Neapolitan.

Stretch and folds: when they help

Stretch and folds mean folding the dough over itself after a rest. They have three aims:

• add extra strength before bulk fermentation;
• redistribute the gases for an even rise;
• increase oxygenation.

The usual rhythm: a covered rest of 20 to 30 minutes, a set of folds, and repeat if the dough is not yet smooth. Stop as soon as it is smooth and barely sticky: an over-tight surface that starts to tear means you have gone too far. What comes next is covered in bulk fermentation, balling and final proof.
