I'm feeding my 100% hydration starter with a 1:4:4 ratio. However, I'm not sure how much to feed to arrive at the amount needed for the dough. I need 10 oz. for my recipe, so thought that for doubling I should feed 5 oz. of starter. I ended up with WAY TOO MUCH starter for my baking project. Any thoughts?
