This recipe creates a basic poolish suitable for many bread recipes. You can easily whisk this up the night before a morning breakmaking session, or even the morning you plan to bake.
In a medium bowl, whisk together the flour and water until a smooth batter forms.
1 cup Bread flour, 1 cup Water
Sprinkle the yeast over the top and let it sit for 5 minutes, until foamy and activated.
¼ teaspoon Active dry yeast
Cover the bowl loosely with plastic wrap and let it ferment at room temperature for 4-6 hours, or until doubled in size and bubbly. The surface may develop a slightly collapsed center.
Your poolish is now ready to use in your bread recipe!
Notes
Use lukewarm water to activate the yeast, but avoid water that is too hot, as it can kill the yeast.
The fermentation time may vary depending on your room temperature. If your kitchen is cooler, it may take closer to 6 hours for the poolish to double.
You can store leftover poolish in the refrigerator for up to 24 hours. However, it may lose some of its activity.
