Description
CO₂ infusion creates fizzy spheres with a fragile membrane through controlled calcium-alginate gelation.
Technical
Carbonation is trapped within alginate spheres through ionic cross-linking of sodium alginate with calcium ions, creating a semi-permeable membrane that maintains internal pressure while allowing gradual CO₂ diffusion.
Culinary Significance
Enables creation of explosive flavor bursts with effervescent textures, revolutionizing cocktail and amuse-bouche presentations.
