Some reader asked me is there any standard calculation for the amount of sourdough starter to use to make bread. From my experience, for rusty or country sourdough bread, usually use very little of starter, around 25%-30% ( starter over total dry ingredients), as to slower down the fermentation and create very nice aroma and mild tangy taste of sourdough bread. As for Asian type of soft bread, based on my own calculation, usually i use about 70-80% (starter over total dry ingredients) , as to speed up the proofing process in order not to get a sour taste of bread. You know it will not taste nice if a soft buns tasted sour right?
This time i baked this batch of red bean buns using homemade red bean paste, and use very simple bread ingredients which easy to make, still resulted soft and nice buns.
