Spherification with calcium chloride creates a thin hydrogel membrane around a liquid core by cross‑linking sodium alginate with Ca²⁺ ions.

Liquid‑nitrogen flash‑freezing instantly solidifies fruit purées at ‑196 °C, creating ultra‑fine ice crystals that lock in flavor and inhibit enzymatic degradation.

Salsa verde’s stability depends on a narrow pH window, moderate temperature, and sufficient shear to keep lecithin‑stabilized oil droplets dispersed.

Garum is a fermented fish sauce produced by enzymatic hydrolysis of fish entrails in a high‑salt brine, generating free amino acids that impart strong umami.

Ultrasonic homogenization creates stable oil‑in‑water emulsions by high‑intensity acoustic cavitation.

Grilling a thick Basque rib steak (txuleta) over charcoal to achieve a medium‑rare interior and a smoky, Maillard‑rich crust.

Rapidly freezes food to –196 °C in 1–5 seconds, vitrifying water and preserving texture and flavor.

Soy lecithin stabilizes air bubbles by forming a flexible interfacial film that reduces surface tension.

Polysaccharide‑based techniques that use ion‑induced cross‑linking to create edible spheres or transparent gels.

Salted and dried egg yolks are preserved by reducing water activity through high salt concentration and low-temperature drying.

Sous‑vide reduction concentrates flavors by gently evaporating water from a liquid at controlled temperatures (60–80 °C).

Cryogenic spherification creates a frozen shell around a liquid core by dropping sodium alginate into a calcium lactate bath cooled with liquid nitrogen.

pH-controlled gelation where calcium alginate spheres form only after acidic ingredients neutralize.

Controlled calcium diffusion creates delayed gelation for liquid-center spheres.

Catalan escalivada is a high‑temperature grilling technique that char‑grills mixed vegetables to produce a smoky, sweet, and slightly bitter flavor profile.

High‑frequency dielectric heating rapidly raises surface temperature to 120–150 °C, creating a Maillard‑driven crust while keeping the interior moist.

Spherification creates liquid‑filled beads by cross‑linking alginate with calcium ions to form a thin hydrogel membrane.

A controlled gelation technique using frozen alginate to delay calcium reaction.

Foamification with nitrogen oxide creates airy microbubbles in liquids by dissolving N₂O under pressure and releasing it rapidly.
