Im looking at a recipe for batter using a soda syphon. Since the term soda syphon, as opposed to cream whipper, is used Id assumed the cartridges shuold be CO2 (recipe doesnt say). But Ive found a few online posts saying that its better to use NO2 cartridges. Any advice here?


Most batters made in a soda syphon/whipper that I have seen, and used myself, use NO2.

A description of what you are making, and which brand of whipper, might allow a better response, as CO2 is sometimes used.

  • My apologies I’ve re-read the recipe and Heston says to use CO2. The recipe involves flour, rice flour, honey, vodka and lager, and a spell in the ‘fridge. It’s an isi syphon, 0.5L. Apparently it has a safety valve. Looking at couple of other recipes for isi and doing the maths on quantities, it looks like halving Heston recipe and using the 0.5L syphon with two CO2 charges is the way to go. I’ll report the results!! – RFlack Jul 6 at 21:29
