Why it works: Celery and mustard are a kitchen classic. They rank in the top 2% of all ingredient pairs, and cooks put them together in 4,169 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
- Potatoes
- Form the bulk of the salad and absorb the sauce's flavour while resting.
- Bacon
- Adds smoky, salty fat and savoury browning flavour to the salad.
- Unsalted butter
- Provides fat and richness, and with flour forms the base of the sauce.
- Unbleached flour
- Thickens the butter into a roux that gives the sauce body.
- Guinness stout
- Supplies the malty, slightly bitter flavour that defines the sauce.
- Sugar
- Balances the sharpness of the stout and mustard with a touch of sweetness.
The step that matters
Stir continuously until the mixture boils. Flour thickens liquid only when heated while stirred; stopping early leaves lumps or a thin sauce, and the starch needs to reach a boil to fully thicken.
Swap the onion
How well each one fits the dish's main ingredients (potato, celery, butter, flour, mustard, sugar, pepper):
