What each ingredient does
- Red currant
- Adds tart, fruity flavour and body to the sauce.
- Butter (in the method)
- Adds fat for richness and a smoother mouthfeel.
- Flour (in the method)
- Thickens the sauce as it heats and the starch swells.
- Onion
- Softens into a mild, savoury base that flavours the liquid.
The step that matters
Boil up after adding the butter and flour. The flour must come to a full boil to thicken the sauce and lose its raw, floury taste. Stopping early leaves the sauce thin and pasty.
