What You Need to Know
The flattening process ruptures cell walls, releasing reducing sugars and amino acids that participate in Maillard reactions at 140-165°C. Simultaneously, rapid starch gelatinization in the batter (60-80°C) creates a porous matrix that facilitates moisture escape.
Creates ultra-crisp textures with greater structural integrity than traditional tempura, allowing for creative plating and sauce adherence.
