Staglio, panetti, and ball weight

Pizza dough is treated differently from bread dough at the division stage. Bread is divided just before final shaping. Pizza is divided into individual balls hours (sometimes days) before baking, with each ball given its own long, separate fermentation. Understanding why, and how to do it well, is one of the larger differences between casual home pizza and serious home pizza.

The Italian terminology

Three terms come up constantly in serious pizza writing:

• Puntata: the bulk fermentation stage. The dough sits as one mass after mixing, typically for 2–8 hours depending on the schedule.
• Staglio: the act of dividing and forming individual dough balls. "Stagliare" is to cut and shape; "staglio" is the action of doing it.
• Apretto: the ball fermentation stage. After staglio, each ball ferments separately until it's stretched and baked. Apretto times range from 4 hours (same-day) to 72 hours (long cold ferment).

Panetti is what the individual dough balls are called. A typical home pizza session involves 4–8 panetti at 220–280 g each.

Why divide so early

Three reasons:

1. 1.Even fermentation per pizza. Dividing into individual balls means each one ferments at its own pace from the same starting point. Dividing at the last minute means the dough nearest the surface has been more exposed to air than the centre: uneven gas distribution.
2. 2.Easier handling. A long-fermented ball is gentler to stretch than a piece torn from a bulk-fermented mass. The ball's tight surface from staglio gives the centre something to push against during stretching.
3. 3.Bake-on-demand flexibility. With pre-formed balls in the fridge, you can pull one out and bake it whenever you want, over the course of an evening or even spread across two days. A bulk-fermented mass that hasn't been divided commits you to a single bake window.

Ball weight by pizza style

Match the ball weight to the pizza you're making.

• Neapolitan, `30–35 cm / 12–14 inch`: 220–260 g. The AVPN spec.
• New York, `35–45 cm / 14–18 inch`: 350–500 g. Larger and slightly thicker than Neapolitan.
• Roman tonda (thin, crisp, `30 cm / 12 inch`): 180–220 g. Less dough means a thinner, crispier base.
• Roman al taglio (rectangular pan, `40×30 cm`): 700–900 g. Pan-baked, much thicker.
• Sicilian / Detroit (rectangular pan, `25×35 cm`): 400–600 g. Thick, focaccia-like base.
• Pizza in teglia (round pan, `30 cm`): 300–400 g. Thicker than Neapolitan, baked in a pan.

These are starting estimates. Personal preference for thickness varies. If your pizzas come out too thin, increase ball weight by 30–40 g. Too thick, decrease.

How to ball a dough

After bulk fermentation, the dough should be soft, pillowy, and full of gas. Tip it gently onto a lightly-floured counter, try not to deflate it more than necessary.

1. 1.Use a bench scraper to divide the dough into pieces of the desired weight. Weigh each one; eyeballing leaves you with one giant ball and several small ones.
2. 2.For each piece: pull the four sides of the dough up and over the centre, like wrapping a parcel. Pinch the top closed.
3. 3.Flip the parcel so the seam is now on the bottom.
4. 4.Cup your hand over the ball and drag it gently across the unfloured part of the counter in small circles. The unfloured surface catches and pulls the ball's outer skin tight.
5. 5.Continue until the ball has a smooth, taut top and a neat pinched seam underneath.

The finished ball should sit on the counter as a smooth round dome. Surface should look glossy. The pinched seam underneath holds the structure together.

Where to put the balls during apretto

Each ball needs its own space. As they ferment, they expand. If they touch each other, they fuse and become hard to separate without tearing.

Two standard storage options:

• Pizza dough box: professional rectangular containers (typically 45×35×7 cm) hold 6–8 balls with separation between them. Stackable. Standard in pizzerias. Available from restaurant-supply stores for €10–25.
• Individual containers: plastic deli quart containers (950 ml / 32 oz) hold one ball comfortably. More awkward but works for small-batch home pizza.

Light dusting of flour or olive oil on the surface where the ball touches the container prevents sticking. Cover the container. Exposed dough develops a leathery skin during apretto.

How long to apretto

Two general approaches:

Same-day room-temperature apretto

Total fermentation 8 hours: bulk for 2 hours, ball, then apretto for 6 hours at room temperature. The ball reaches peak by hour 6 and is stretched and baked. AVPN-traditional schedule.

Cold ferment apretto

Total fermentation 24–72 hours: bulk for 2 hours at room temperature, ball, then apretto for 22–70 hours in the fridge. Take balls out 2–4 hours before baking to come to room temperature. The standard for serious home pizza making: better flavor, easier handling, more schedule flexibility.

How to tell when a ball is ready to stretch

1. 1.Volume increase: the ball should have grown noticeably during apretto, 30–80% larger than its original size after balling.
2. 2.Surface: smooth, slightly domed, possibly with small visible bubbles around the bottom edge.
3. 3.Texture: when you press a fingertip in, the dough should yield easily and spring back slowly. A ball that's hard and resists pressure is under-fermented; one that's slack and doesn't spring back is over-fermented.

Common ball-management mistakes

Balls too small

Underweight balls produce thin, brittle pizzas with no cornicione. If your pizzas come out flat and crispy without the puff at the edges, increase ball weight by 30–50 g and re-test.

Balls touching during apretto

Pizzas baked from balls that fused during apretto have torn edges where you separated them. The torn area doesn't form a good cornicione. Give each ball more space.

Stretching a cold ball straight from the fridge

Cold dough resists stretching. Take balls out 1–2 hours before stretching to let them warm up. They become much more cooperative. The fridge-cold cornicione also doesn't puff as well in the oven as a room-temperature one.

The takeaway

Divide pizza dough early, after a short bulk, hours before baking. Match ball weight to pizza style. Ball with a tight surface, store with separation, ferment for 6–72 hours depending on the schedule. The discipline of treating each ball as its own little fermentation is most of what separates serious home pizza from the casual kind.
