Why it works: Shallot and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 5,898 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shallots
- Provide the sharp, aromatic onion flavor that defines the sauce.
- Gravy
- Supplies the savory body and liquid base for the sauce.
- Vinegar
- Adds acidity that brightens the sauce and balances the rich gravy.
The step that matters
Simmering after the boil. Simmering for the full 30 minutes lets the vinegar's sharpness mellow and the shallots soften and release flavor. Boiling too hard can reduce the sauce too quickly and make it harsh or overly concentrated.
