I had the same problem when working on getting San Francisco sourdough correct. I realized the trick is to leave your starter on the counter for longer. I took my starter out of the fridge and left it on the counter for 3 or 4 days until it really started getting funky smelling. This helps develop the lactic acid cultures (sourness from lactic acid) and Acetobacter cultures(sourness and aroma from acetic acid/vinegar). The Acetobacter cultures eat ethanol (the clear hooch/liquid that forms) that yeast produce when metabolizing sugars. Leaving it out of the fridge helps develops flavor, sourness and aroma because fridge tempuratures stifle growth. Start with this and use you regular amount of starter as a baseline and then add or subract starter as to your preference. I hope this helps. P.S. don’t let your significant other accidently dump out your starter because they think something went off in a jar on your counter :l
I think once in while is what i was doing. This was back in 2014. Probably depends on how often you’re making bread too.
The way I figure it with sourdough and especially San Francisco sourdough, is the miners who were making it originally were leaving their starters unrefrigerated and probably feeding their starters every day. They’d make their dough in the morning and bake their bread in the evening after work, so everything is getting constantly refreshed.
If you’re not making it constantly I’d just feed it leave it out for a day to normalize and put it into the fridge to slow everything down and repeat when you use it again.
I see baking as an art and a science. Everything is an experiment and the kitchen is your lab and your studio. You’re the master of your kitchen and have free reign to try anything. Why not split your starter and test out multiple approaches to see what works best in your opinion? Everything you make will turn into bread barring burning it or forgetting the salt. If you make more loaves than you eat just share it with others. Turns out people innately enjoy eating bread. The only hard rules are salt your bread and don’t burn it.
