Biga (pronounced bee-gah) is an Italian secret weapon in the arsenal of artisan bakers. This pre-fermentation technique, also known as pâte fermentée in France, involves creating a small dough starter with a long, slow fermentation.
In a large bowl, whisk together the flour, water, and yeast until a shaggy dough forms.
1 cup All-purpose flour, ½ cup Water, ½ teaspoon Instant yeast
Cover the bowl loosely with plastic wrap and let the dough rest at room temperature (around 70°F/21°C) for at least 12 hours, but preferably 16-18 hours.
During this time, the biga will rise slightly, become bubbly, and develop a slightly sour aroma.
It's ready to be used in your bread recipe. You can use it immediately or store it in the refrigerator for up to 3 days.
Notes
Use cool or room temperature water for optimal yeast activity.
Ensure your bowl is large enough to allow the biga to double in size during fermentation.
The fermentation time can vary depending on room temperature. The biga is ready when it has doubled in size and is full of bubbles.
