Great question, George. Here's how we suggest going about increasing your starter in our Sourdough Tips & Recipes booklet: "To build a larger quantity of starter, simply increase the amount of flour and water you add at each feeding, being sure to keep the flour and water in the same ratio. This should allow you to make enough for a large recipe with some left over to feed and maintain. For example, the last feeding before you bake, save 8 ounces (1 cup) of sourdough starter, and feed it 8 ounces (1 cup) of water and 8 ounces (2 scant cups) of flour." Mollie@KAF
