Description
Creates thin, delicate liquid spheres with gelled membranes using calcium lactate gluconate.
Technical
Calcium ions from lactate gluconate cross-link alginate polymers at the liquid's surface, forming a semi-permeable membrane while maintaining liquid interiors. The lower calcium concentration allows slower, more controlled gelation than calcium chloride.
Culinary Significance
Enables encapsulation of delicate flavors (citrus, alcohol) that would denature in traditional spherification.
