How it works:
This is a variation of the seltzer bottle !
Pour in HEAVY cream, then put the charging cartridge into it's carrier and screw it in. The cartridge is filled with approximatly 3 litres of Nitrous Oxide which is released into the container containing the cream. Shake well, and keep in the refrigerator - shake well again before using.
Problems: the Nitrous cartridges are hard to find, and rather pricey. also - eventually the O-ring seals start to leak and then the whole unit stops working properly. All this drama for Whipped cream?
Best Solution: ( IMHO ) = Rediwhip.
