What each ingredient does
- Butter
- Browns and toasts its milk solids, creating the nutty, deep flavour that defines the sauce.
- Vinegar
- Adds a sharp acidity that brightens and balances the rich, toasty butter.
The step that matters
Heating the butter until dark brown. Butter contains milk solids that darken and toast as the water cooks off. Stopping too early leaves the flavour flat, while going too far turns the solids bitter and black. Watch the colour closely and remove the pan as soon as the butter reaches a dark brown.
