What each ingredient does
- Gentian root
- Provides the bitter flavour that defines the bitters.
- Seville orange peel
- Adds aromatic citrus oils that give the bitters their orange fragrance.
The step that matters
Steeping with boiling water. Hot water draws bitter compounds and aromatic oils out of the gentian root and peel. Steeping for the full two hours lets the flavours extract evenly, so the final bitters are neither weak nor harsh.
