What You Need to Know
Sodium hydroxide solution (pH ~11-12) breaks down fish proteins via hydrolysis, converting collagen to gelatin while dissolving hemicellulose in remaining connective tissue. The process creates a gel-like matrix of partially hydrolyzed proteins.
Creates a distinctive translucent texture and mild flavor, requiring careful preparation to remove residual lye before consumption.
