What each ingredient does
- Butter
- Provides richness and a smooth, flowing body to the sauce.
- Fennel
- Adds a light anise-like aroma and flavour to the butter.
The step that matters
Adding the fennel just before the butter boils. Butter that boils turns foamy and its milk solids can brown and turn bitter. Adding the fennel before boiling keeps the sauce smooth and fresh-tasting, and a short simmer of 1-2 minutes is enough to release the fennel's flavour.
