Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Provides fat and richness, carrying flavour and giving the sauce a smooth, silky mouthfeel.
- Flour
- Thickens the sauce as its starch swells in the hot liquid, giving body to the sauce.
- Brandy
- Adds aroma and a warm, complex flavour once stirred in off the heat.
- Sugar
- Adds sweetness that balances the richness of the butter and the warmth of the brandy.
The step that matters
Add the water gradually while stirring constantly. Flour mixed into hot fat clumps if liquid is added too fast. Adding the water slowly while stirring disperses the starch evenly, so the sauce becomes smooth and thickens without lumps.
