What each ingredient does
- Melted butter
- Forms the fat base of the sauce, giving it richness and a smooth, flowing texture.
- Fennel
- Adds a light aniseed aroma and flavour to the warm butter.
The step that matters
Adding the fennel to nearly boiling butter. Fennel's aromatic compounds release into hot fat, so the sauce gains flavour quickly. Simmering too long can overheat the butter, causing it to brown or separate and dulling the fresh fennel taste.
