Gourmet Whip is designed by the Austrian brand iSi. The siphon enables completely new ways of cooking by bringing out new flavours and textures. It's perfect for skimming soups, purees and mousses as well as whipping cream for dessert. The siphon is made of a solid stainless steel and silicone construction that is dishwasher safe and holds 1 litre. It is easily charged with gas cartridges of N2O, nitrous oxide or CO2, carbon dioxide. The siphon can extend the shelf life of most foods and can be stored in the refrigerator for several days without the contents going bad.
