For the Buttermilk Kitchen's 105-Year-Old Sourdough Starter: Mix 1 pound of water and 1 pound of flour to form a smooth paste. Put into a new plastic container cover and let stand in a calm place that has a constant temperature of 50-65 degrees for two weeks. Check periodically for mold and remove if you see some. It should start to bubble after 10 to 12 days. When it's very bubbly its time to "feed" it.
Reserve 1 pound of bubbly starter and discard the rest. Mix the reserved starter with the remaining 1 pound of bread flour and 1 pound of water. Do this everyday for 1 week and your starter will be ready. When your amount of starter gets low, continue to "feed" it.
