Recently I was invited by Jim Lahey to his bakery for a day finalizing and testing formulas for his upcoming book on no-knead sourdough. It was interesting to watch. And gave me an opportunity to get a richer perspective of Jim’s kitchen philosophy. Besides talking bread, he shared his current obsession, the off-Broadway musical “Hamilton.” The soundtrack accompanied our mixing a rack of namesake buns Jim created in honor of this production and founder of this country’s monetary system. Here are some of the look behind the scenes.
