Hello! I just moved to a new town without any good sourdough bread, and so I decided to learn to make my own! I found a local bed and breakfast that gave me starter that the owner uses to make sourdough biscuits. Her instructions say to feed with flour, sugar, and milk, and she gave me a recipe for making biscuits with that. But I want to make bread. Can I just start feeding the starter with flour and water instead, or will it react poorly to this change in diet? Thank you!
