I don't think it's going to make anything fizz, I have read some people have been trying it for some sort of a flavor booster but can't confirm, what are you looking for this to do for you in your mix..
I read the same thing about using triacetin from Ginger Booth. Supposedly gives cola, root beer, etc. that fizzy mouth feel. I have triacetin, but haven't used it yet.
IME, malic makes things SOUR. Maybe in flavors we associate sourness with fizziness, it would have that effect. A citrus flavor might be more like citrus soda, eg, with a little malic acid.
Crazy chef if you do get around to using that triacetin would you post the results. I have heard the same and have yet to find a fizz for a few recipes. I have tried champagne and colas with sub par results. Thanks.
