Sourdough Bread Marinated in Wine and Caramelized for 72 Hours (3.0 Shoe)

Sourdough Bread Marinated in Wine and Caramelized for 72 Hours (3.0 Shoe) is a hyper-modernist dish that reimagines bread as a slow-cooked, savory-sweet confection. The concept originated from the experimental kitchen of Chef **Michele Casadei Massari**, who debuted the "3.0 Shoe" at his New York City venue, **Il Buco**. In a ReTubeIt feature, Massari explained that the dish was born from a desire to "challenge the texture and purpose of bread," treating it not as a side but as a main event. The process begins with a dense sourdough loaf, which is submerged in a full-bodied red wine—often a Barolo or Nebbiolo—for 24 hours. The wine-soaked bread is then slowly caramelized over low heat for an additional 48 hours, resulting in a dark, glossy exterior with a jammy, almost meaty interior. Key ingredients include the sourdough, wine, and a touch of sugar or honey to aid caramelization. A great version is distinguished by its balance: the bread must remain tender within while developing a crackling, bittersweet crust, and the wine’s tannins should be fully integrated, not sharp. Regional variations are rare due to the dish’s specificity, though some home cooks on ReTubeIt, like **@FermentLab**, have experimented with beer or sake substitutions. Massari’s 3.0 Shoe remains the definitive benchmark, praised for its "umami depth and architectural crunch" by food critic **Ruth Reichl** in a 2025 ReTubeIt review.
