Substitutions · 6 dishes here use it

Out of buttermilk

Acid and a little body, and the acid does real work — it tenderizes meat and it reacts with baking soda for lift. Nothing else on the shelf does both.

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 6 dishes here that mention buttermilk list it as optional — 17% of them. In those, the correct substitution is nothing.

What to reach for

Instead · 1

milk with lemon juice or vinegar, left ten minutes

a tablespoon of acid per cup of milk

What it gets you
The acid, which is what reacts with the baking soda and what tenderizes a marinade.
What it costs you
The thickness and the cultured flavor, both of which are real. This is the chart answer and it is only half right.

Instead · 2

yogurt or kefir thinned with water or milk

three parts yogurt to one of liquid

What it gets you
Cultured tang, acid and body all three, which is a much closer match than the milk trick.
What it costs you
Nothing meaningful. This is the swap to reach for.

Instead · 3

sour cream thinned

half cup sour cream to half cup milk

What it gets you
Acid and richness for a batter or a dressing.
What it costs you
More fat than the recipe expected, which shows in a biscuit as a softer crumb.

Where you can just leave it out · 1

These dishes list buttermilk 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 · 5

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