Simple No-Knead #quarantinystarter Sourdough Bread
Makes 1 loaf.
Note: This dough must be prepared in advance. Levain is the building block for leavened bread. From Andrew Janjigian of Cook's Illustrated magazine and America's Test Kitchen and adapted from King Arthur Flour. "Volume measures are approximate here," he said. "King Arthur all-purpose flour is the ideal flour for this recipe, but other bread flours will work as well (King Arthur all-purpose flour is closer in protein content to other bread flours than it is to other all-purpose flours). If your starter is already on a large enough scale to yield 30 grams — plus extra for refreshing, don't forget that! — then you can skip the levain hydration step and mix it into the dough directly. If your kitchen is very cold, you can increase the amount of your levain to 50 grams. In the heat of summer, you can get away with as little as 5 grams."
For 100% hydration levain (see Note):
• 40 g (1/3 c.) bread flour or high-protein all-purpose flour (see Note)
• 40 g (3 tbsp.) lukewarm (75 degrees) water
• 20 g (4 tsp.) sourdough starter (see the formula below)
