When you are getting it ready for baking, if you’d like to bake more than one loaf or make a recipe that uses more than 50 to 70 grams of starter, just feed it double: 100g of both water and flour.
Easy — simply feed it more! When you are getting it ready for baking, if you’d like to bake more than one loaf or make a recipe that uses more than 50 to 70 grams of starter, just feed it double: 100g of both water and flour. If you need even more than that, when the starter has peaked, feed it again. Repeat until you have the amount of starter that you need.
