What You Need to Know
The smoldering hay (typically timothy or meadow fescue) undergoes depolymerization at 280-320°C, releasing furfural and 5-hydroxymethylfurfural. These react with amino acids in the food surface via Strecker degradation. The grass' inherent potassium salts act as natural catalysts for caramelization.
Creates a crisp crust with alternating caramelized and smoked zones. Traditionally used for root vegetables and freshwater fish. Modern chefs employ hay embers to finish duck breasts, creating a flavor bridge between smoking and searing.
