Glossary

The terms you'll meet in biga pizza dough recipes, explained simply.

Active dry yeast
Dried yeast in granules, usually dissolved in some of the water first. Use about 0.4 g for every 1 g of fresh yeast. See fresh, active dry or instant yeast.
Appretto
Italian for the second rise: the fermentation after the dough is divided and shaped into balls, until they are ready to stretch. Also called ball fermentation.
Baker's percentage
A way of writing a recipe where every ingredient is a percentage of the total flour, which counts as 100%. 70% hydration means 700 g of water per 1 kg of flour. It makes recipes easy to scale and compare.
Bassinage
Adding part of the water late in mixing, a little at a time, once the dough has developed some strength. It helps a dough take more water without turning slack.
Biga
An Italian pre-ferment: a stiff mix of flour, water (usually around 50%) and a little yeast, mixed without kneading and fermented before it goes into the final dough. See how to make biga pizza dough.
Canotto
Italian for "dinghy": the contemporary Neapolitan style with a very tall, airy rim, typical of high-hydration and 100% biga doughs.
Coil fold
A gentle way to strengthen a soft dough during its rest: lift it from the middle so it folds under itself, turn the container and repeat. It builds structure without more mixing.
Cornicione
The raised rim of a Neapolitan pizza. A well-fermented biga dough gives a puffy, airy cornicione.
Diastatic malt
Malted grain powder with active enzymes that turn starch into sugars during fermentation. It helps the crust brown in ovens that don't get very hot.
Final dough
The dough made by mixing the fermented biga with the rest of the ingredients: water, salt, oil, a small yeast boost and, if the biga holds only part of the flour, more flour. Also called impasto.
Fresh yeast
Soft, crumbly blocks of live yeast, also called compressed or cake yeast. The usual choice in Italian biga recipes. It keeps for about two weeks in the fridge.
Hydration
The water in a dough as a percentage of the flour. Neapolitan doughs are usually 60–75%. In this calculator, total hydration includes the biga's water.
Instant dry yeast
Fine dried yeast that can go straight in with the flour or water. Use about 0.33 g for every 1 g of fresh yeast.
Leopard spotting
Small dark spots on the rim of a pizza baked in a very hot oven, a sign of good fermentation and strong heat.
Pasta di riporto
A piece of dough kept back from a previous batch and added to a new one for flavour. It isn't needed with a 100% biga, which already does that job.
Poolish
A liquid pre-ferment with equal weights of flour and water (100% hydration). Wetter and faster than a biga, with a milder, more lactic flavour.
Pre-ferment
Part of the flour, water and yeast fermented ahead of time and then added to the final dough. Biga and poolish are pre-ferments.
Puntata
Italian for the first rise, or bulk fermentation: the dough rests as one mass after mixing, before it is divided into balls.
Spiral mixer
A mixer whose spiral hook and bowl both turn, developing dough quickly with little heat. See mixing the final dough in a spiral mixer.
W (flour strength)
A measure of how strong a flour is, from a lab test called the alveograph. Higher W flours hold up better in long fermentations; Italian pizza flours often state it on the bag.
Yeast boost
The small amount of yeast added to the final dough, around 0.1% of the flour. Most of the rise comes from the yeast that grew in the biga; the boost helps it along.
