Next-Day Rye Sourdough Starter

Some sours utilize rye flour and add a bit of onion, a classic old touch that contributes greatly to the flavor and encourages fermentation. This is a fast version of rye bread starter that uses a packaged dry culture to add flavor. It has a wonderful aroma evocative of all that sourdough baking epitomizes. This starter is ready to use after thirty-two hours. Begin it early in the morning, and you’ll have Sourdough Rye Bread for dinner the following night.
