Why it works: Mushroom and shallot are a kitchen classic. They rank in the top 4% of all ingredient pairs, and cooks put them together in 1,982 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
- Add aromatic flavour and a mild savoury sweetness as they steep in the liquid.
- Mushroom ketchup
- Contributes deep savoury umami flavour that forms the base of the sauce.
- Walnut ketchup
- Adds rich, savoury depth and body to the sauce's overall flavour.
- White wine vinegar
- Provides acidity that brightens the sauce and helps preserve it.
The step that matters
Macerating for 14 days. Long steeping lets the flavours from the spices and shallots slowly extract into the liquid. Stopping early leaves the sauce thin and harsh, while the warm spot keeps extraction steady.
Swap the white pepper
How well each one fits the dish's main ingredients (walnut, ketchup, mushroom, port wine, shallot, clove, white wine):
