Step 1

Day 1: Mix together the flour and water in a medium-sized bowl, stirring until thoroughly combined. Cover the bowl, and let the mixture rest overnight at room temperature., Day 2: Discard half the starter, and feed the remainder with 1/2 cup + 1 tablespoon (128g) cool water and 1 cup (121g) Measure for Measure flour., Days 3, 4, 5... Repeat the process from Day

Step 2

Sometime between days 5 and 10, you'll notice that within several hours after feeding the starter will have grown in size to between 2 1/4 and 2 3/4 cups. At this point it's ready to use in your recipe. If it takes longer than this, simply keep repeating the once-a-day feeding process until it matures fully; bubbling nicely, and doubling in size within several hours after feeding.
