Pâte fermentée, literally translating to "fermented dough" in French, is a unique technique used in bread baking. Unlike a sourdough starter which relies on wild yeasts and bacteria, pâte fermentée involves pinching off a portion of fully mixed bread dough and allowing it to ferment separately.
In a small bowl, whisk together the bread flour, water, and yeast until a shaggy dough forms.
½ cup Bread flour, ½ cup Water , ¼ teaspoon Active dry yeast
Cover the bowl tightly with plastic wrap or a damp kitchen towel.
Let the dough ferment at room temperature for 8-12 hours, or until doubled in size and bubbly. The surface may appear slightly cracked, that's okay!
Notes
Use lukewarm water to activate the yeast, but avoid water that is too hot, as it can kill the yeast.
The fermentation time can vary depending on your room temperature. If your kitchen is cool, it may take closer to 12 hours for the pâte fermentée to double.
Once the pâte fermentée is ready, you can use it immediately in your bread recipe or store it in the refrigerator for up to 24 hours.
