Hello! I am new to sourdough. I was given a starter that takes 1/2 cup of sugar, 3 tbsp of potato flakes, 1 cup of flour, plus 1 cup of water to be fed daily x's 2. Can I change the feeding without disturbing the starter? I would like to be able to feed just flour and water daily. Can I stop feeding the sugar and potato flakes?
Any help is appreciated.
You certainly should forget about the potato flakes and sugar.
You also really should read the Beginners Tutorials on this site. You can access them from the Home Page in the right hand column. They give an excellent run-down on the whole process, from creating your starter to making and baking your bread.
Good luck with your projects.
