What You Need to Know
Sake lees (Saccharomyces cerevisiae-rich byproduct) provide proteolytic enzymes that partially break down fish proteins, while alcohol-soluble flavor compounds penetrate tissue. The subsequent Maillard reaction and lipid oxidation during frying create complex flavor profiles.
Creates a crisp exterior with unusually tender flesh and deep savory-sweet notes distinct from standard tempura.
