Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Clear brown stock
- Forms the savoury liquid base that gives the sauce its main body and flavour.
- Arrowroot
- Thickens the sauce as its starch swells and sets when heated, giving a glossy texture.
- Claret
- Adds acidity and wine depth that balances the richness of the stock.
- French mustard
- Adds sharp pungency that cuts through the richness of the sauce.
- Worcestershire sauce
- Adds savoury, tangy depth and umami to the sauce.
The step that matters
Bringing the arrowroot mixture to a boil. Arrowroot must be fully mixed smooth with the claret first, or it will form lumps. It thickens as its starch heats, but prolonged boiling or stirring can thin it again, so bring it to the boil and remove it promptly once thickened.
Swap the arrowroot
