When I was younger I used to use sourdough starters and friends used to give me friendship cake starters and the like. I had one starter that lasted over a year.
My first batch will be from Chef Emeril Lagasse’s recipe for a Potato Water Sourdough Starter. If it works for me then I will start playing around with my own ideas. I have a few concerns because our house is an 130 year old, drafty, Victorian gem.
Once I get through doing this at home then I will try using sourdough to make bread on a backpacking or paddling trip.
