Since most of us are no strangers to force carbonating liquids, and I have a 20lb co2 tank dedicated to force carbonating kegs of beer, as well as a tendency to go through a good amount of club soda (a la Schwepps), I was thinking about doing my own club soda at home, save on the cost of actually buying it, as well as reusing some of that nasty plastic before getting it to the recyclers.
However, all of my attempts at finding a recipe for club soda have resulted in nothing but what to use club soda *in*. The only things I've found is a suggestion of adding a bit of baking soda to seltzer water, or that club soda may contain in unspecified amounts:
sodium bicarbonate (baking soda)
Neither of which are very useful. Does anyone have any experience with doing their own club soda? Found something that makes a passable club soda using tap water + some of the above or even using distilled water and a specific ingredient list or kit?
