Description
Creates encapsulated liquids with two distinct gel layers for enhanced stability.
Technical
Sequential ionic gelation forms concentric membranes: an outer alginate-calcium matrix and inner reverse-spherification layer. The process leverages diffusion-limited crosslinking of sodium alginate (C6H7NaO6)n with divalent cations.
Culinary Significance
Enables creation of durable liquid-filled spheres that withstand plating and temperature variations better than single-layer spherification.
