Description
Sous‑vide ice‑cream is a frozen dessert produced by pasteurising a custard mixture, vacuum‑sealing it, and holding it at low temperatures to control fat crystallisation and ice‑nucleation.
Technical
The brief 55 °C pasteurisation step denatures proteins and kills pathogens while preserving flavor compounds. Subsequent vacuum‑sealed hold at 2–4 °C allows fat globules to coalesce into fine crystals, and the final low‑temperature hold at −5 °C to −7 °C promotes the formation of sub‑50 µm ice crystals, yielding a silky texture.
