armagnac or any decent brandy

- What it gets you

- What it costs you

Substitutions · 16 dishes here use it
Out of cognac
Grape spirit with fruit and oak, which makes it rounder and less spiky than whiskey in the same drink. It goes soft under too much sugar, so it wants acid or bitterness beside it.
Everything below is judged against that job. A swap that covers it is a swap; one that only looks similar is not.
1 of the 16 dishes here that mention cognac list it as optional — 6% of them. In those, the correct substitution is nothing.
Functional substitution system
Replace the job, then correct the side effects
For cognac, the page's working definition is: Grape spirit with fruit and oak, which makes it rounder and less spiky than whiskey in the same drink. It goes soft under too much sugar, so it wants acid or bitterness beside it. The swap cards below are judged against that job rather than visual resemblance.
1 · Job
What is the missing ingredient doing?
2 · Candidate
Choose the shelf item that replaces that function.
3 · Side effects
Check water, fat, salt, acid, sweetness, and texture.
4 · Small test
Change a spoonful or small portion first when possible.
5 · Correct
Taste again and move only the axis that is still wrong.
What to reach for
Instead · 2
aged rum
one for one
- What it gets you
- Barrel age, fruit and sweetness in a stirred drink or a flambe.
- What it costs you
- The grape. Rum is sweeter and heavier and it will show in a sidecar.
Instead · 3
bourbon
one for one
- What it gets you
- An aged spirit that stands up to citrus and sugar the same way.
- What it costs you
- Delicacy. Bourbon is louder, sweeter and more oak-forward than cognac ever is.
Where you can just leave it out · 1
These dishes list cognac 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 · 15
These need it and are short enough that nothing hides: 4 required ingredients or fewer. Make the swap a decision rather than a repair.
Check what else is in the pan
The company cognac keeps in this library, counted off required ingredients. A swap that argues with the top two is the wrong swap, whatever a chart says.
