Description
A delicate shellfish extraction method optimizing flavor without bitterness.
Technical
Low-temperature steeping (60-80°C) of crushed crustacean shells promotes extraction of savory amino acids (glutamate, glycine) while minimizing sulfurous thiazole formation from overheating.
Culinary Significance
Creates a cleaner shellfish essence than boiling, ideal for refined sauces and poaching liquids.
