What each ingredient does
- Butter
- Browns and toasts to give a nutty, deeply savoury flavour and aroma.
- Vinegar
- Adds acidity that sharpens the rich, toasted butter.
The step that matters
Heat the butter until dark brown. Butter has milk solids that brown as the water cooks off, producing nutty flavour compounds. If heated too briefly the flavour stays flat, but if it goes past dark brown it turns bitter and burnt, so the cook needs to watch the colour closely.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
