Description
Clarifies liquids by trapping impurities in an agar gel matrix.
Technical
Agar polysaccharides form a thermo-reversible gel that captures suspended particles when set, then releases clarified liquid upon melting below 40°C while retaining impurities in the gel structure.
Culinary Significance
Produces brilliantly clear consommés without traditional raft methods, preserving delicate flavors.
