Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter

- Flour
- Thickens the sauce as it cooks with the melted butter.
- Sugar
- Adds sweetness that balances the brandy.
- Brandy
- Adds its distinctive aroma and flavour to the sauce.
The step that matters
Gradually add the water. Adding liquid slowly while stirring keeps the flour smooth and prevents lumps as the starch hydrates and the sauce thickens.
