I'm looking at a recipe for batter using a soda syphon. Since the term soda syphon, as opposed to cream whipper, is used I'd assumed the cartridges should be CO2 (recipe doesn't say). But I've found a few online posts saying that it's better to use NO2 cartridges. Any advice here?
Most batters made in a soda syphon/whipper that I have seen, and used myself, use N20. Though, often, when the goal is aeration, CO2 is used.
A description of what you are making, and which brand of whipper, might allow a better response.
