Flash‑Frozen Fruit Caviar (Spherified Fruit)

Description

Flash‑frozen fruit caviar combines cryogenic freezing with spherification to create burst‑of‑flavor micro‑spheres.

Technical

Liquid nitrogen rapidly freezes fruit, preventing large ice crystals and preserving cellular integrity. A 1–2 % sodium alginate solution is then cross‑linked with 0.1–0.2 % calcium chloride, forming a thin calcium‑alginate hydrogel membrane around each piece. The resulting gel encapsulates the fruit juice, which is released when the delicate shell ruptures on the tongue.
