Why it works: Butter and sugar are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 98,233 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and a smooth, rounded body to the sauce.
- Sugar
- Sweetens the sauce and, creamed with butter, adds body.
- Claret
- Provides the main liquid and the wine flavour and acidity.
- Arrowroot or cornstarch
- Thickens the claret as it heats, giving the sauce its body.
The step that matters
Cooking the starch into the claret. Arrowroot or cornstarch only thickens fully when heated, so cooking it in the claret for the full minute lets the starch swell. Without this, the sauce stays thin or may taste starchy.
