Out of grapefruit

Bitter as well as sour, which makes it the one citrus that can carry a drink on its own. It is also the most variable — taste it before you build around it.

Everything below is judged against that job. A swap that covers it is a swap; one that only looks similar is not.

What to reach for

Instead · 1

orange plus a splash of lemon

three parts orange juice to one of lemon

What it gets you
Sweet citrus with acid behind it, at roughly grapefruit's balance.
What it costs you
The bitterness, which is the whole reason grapefruit is in a paloma or a salad.

Instead · 2

pomelo or blood orange

one for one

What it gets you
A close citrus relative with the same segments and the same use on a plate.
What it costs you
Pomelo is much sweeter and drier; blood orange has no bitterness at all.

Instead · 3

orange juice plus a dash of bitters or a splash of campari

one for one on the juice, two dashes or a quarter ounce

What it gets you
The sweet-bitter shape a grapefruit drink is built on.
What it costs you
The specific pith aroma, and campari brings its own color and sugar.

Where the swap will be tasted · 11

These need it and are short enough that nothing hides: 4 required ingredients or fewer, which makes grapefruit 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 grapefruit keeps in this library, counted off required ingredients. A swap that argues with the top two is the wrong swap, whatever a chart says.
