What each ingredient does

Butter
Browned to a very dark stage, giving the sauce its nutty, toasted flavour.
Vinegar
Adds sharp acidity that balances the rich, dark butter.

The step that matters

Heating the butter to nearly black. Butter must be taken well past golden until the milk solids turn very dark, which builds the toasted flavour. Heating too briefly leaves the sauce pale and bland, while going too far can make it bitter and burnt.
