Anyone have expertise in production baking? I am a chef with little natural leavening baking experience. I can make a mean loaf with commercial yeast, but alas, cannot seem to get the the "old fashioned" thing down. I am determined to do what ever it takes to make the absolute most natural and best loaf in las vegas and in my restaurant. My main complaint is that the loafs are too heavy. If I try proofing them for longer they are lighter but become "over-proofed". i.e. extra heavy crust that is extremely hard and crunchy. Please let me know if any of you can lend me a hand in troubleshooting my production.
