Biga or poolish for pizza: differences and two starter recipes

Biga is a relatively stiff preferment; poolish commonly uses equal weights of flour and water. Both use yeast. Neither is sourdough, and neither guarantees better pizza than a well-managed direct dough. Temperature, flour and readiness matter more than the name.

What changes between them?

A stiff biga forms a crumbly mixture and needs careful incorporation into the final dough. Poolish is loose, easy to mix and visibly bubbly as it matures. They distribute water differently, so calculate the final recipe from all flour and water, including the preferment.

First establish a direct dough or a cold-fermented method. Read the flour guide before attempting a longer schedule.

Example one: poolish pizza dough

For the poolish, mix 200 g flour, 200 g water and 0.2 g instant yeast. Cover with room for expansion and begin observing at about 12 hours around 20°C; it may need roughly 12–16 hours. Look for a well-aerated surface close to peak, not a collapsed, exhausted mixture.

For the final dough, add 300 g flour, 125 g water, 12 g salt and 0.5 g instant yeast. The total is 500 g flour and 325 g water: 65% hydration. Stir the poolish into the final water, mix in the remaining ingredients and develop a cohesive dough.

Example two: biga pizza dough

For the biga, combine 200 g flour, 90 g water and 0.5 g instant yeast. Mix only until the flour is hydrated into rough, crumbly pieces, rather than kneading a smooth final dough. Cover and use a controlled cool environment around 18°C, observing over roughly 14–18 hours.

For the final dough, add 300 g flour, 235 g water, 12 g salt and 0.5 g instant yeast. Again, the totals are 500 g flour and 325 g water. Break the mature biga into the water, incorporate the remaining ingredients and knead until no dry lumps remain.

Finish according to dough behaviour

After final mixing, allow a covered rise until expanded, then divide into roughly three equal balls and let relax until puffy and stretchable. Several hours at around 22°C may be needed, but the preferment's condition changes this. These examples are starting schedules, not fixed deadlines.

Tiny yeast quantities need a precise scale. Do not estimate 0.2 g from a teaspoon. In a 28°C summer kitchen, neither cool preferment schedule should simply be left unchanged.

Common problems

• Collapsed poolish: check temperature, yeast and waiting time.
• Dry biga lumps: improve hydration during mixing and incorporation.
• Weak final dough: reassess flour, maturation and water, not only kneading.
• Sticky transfer: relax the dough, limit wet topping and work promptly.

Use pizza troubleshooting and peel technique to separate dough problems from baking problems.

Which should you choose?

Poolish offers visible readiness clues and straightforward mixing. Biga suits cooks who can manage its cool maturation and firmer mixing. Choose one, record the conditions and repeat before comparing the next.
