Step 1: Feed the starter in preparation for Day 1. Add flour and water and let it sit out overnight.
Day 1: Measure 1 cup of "fed" starter to 1 1/2 cups lukewarm water and 3 cups flour. Stir vigorously. Let sit out 4 hours then into the fridge overnight. Refrigeration of the dough causes more acetic acid to form yielding a more tangy taste.
