Substitutions · 96 dishes here use it
Out of soda
Carbonation is a texture and it is the first thing you lose. Build in the glass, pour it down the side, and stir once at most — every extra stir is bubbles you paid for and threw away.
Everything below is judged against that job. A swap that covers it is a swap; one that only looks similar is not.
17 of the 96 dishes here that mention soda list it as optional — 18% of them. In those, the correct substitution is nothing.
What to reach for
Instead · 1
tonic water
one for one
- What it gets you
- The bubbles and the same dilution, which is the mechanical half of the job.
- What it costs you
- It is sweet and bitter. Any drink you build on it needs less sugar and will taste of quinine whether that suits it or not.
Instead · 2
sparkling mineral water
one for one
- What it gets you
- Everything soda water does, and often with a firmer bead that holds up longer in the glass.
- What it costs you
- A faint mineral taste, which in a delicate highball is noticeable and in most drinks is not.
What none of them do
Flat water is not a substitute. The bubbles are carrying aroma up out of the glass, and a highball made with still water is a diluted drink rather than a long one.
Where you can just leave it out · 17
These dishes list soda as optional. They were written to work without it, so no ratio is needed and nothing has to be bought.
Where the swap will be tasted · 70
These need it and are short enough that nothing hides: 4 required ingredients or fewer, which makes soda a quarter of what is in the pan. Make the swap a decision rather than a repair.

Check what else is in the pan
The company soda keeps in this library, counted off required ingredients. A swap that argues with the top two is the wrong swap, whatever a chart says.
