Why it works: Parsley and shallot match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 3,737 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
- Whitings (in the method)
- Main protein, cooked gently in the brine so the flesh turns opaque and stays tender.
- Milk
- Added to the poaching liquid, it contributes mild richness and a softer flavour to the fish.
- Butter
- Melted fat that carries flavour and gives the sauce a rich, smooth base.
- Flour
- Starch that swells in the hot butter and thickens the sauce, giving it body.
- Cream
- Adds richness and body to the sauce as it thickens.
- Shallots
- Add a mild, sweet onion-like aroma to both the brine and the sauce.
The step that matters
Thicken the mixture with cream. Flour thickens only when it is hot and fully mixed into the butter, so the starch swells evenly. Blending it well before adding the cream helps the sauce stay smooth and avoid lumps.
Swap the onion
How well each one fits the dish's main ingredients (parsley, shallot, milk, butter, flour, pepper, cream):
- Chivefits better
- Leekfits better
- Arrowrootfits better
- Onionthe original
Fit is the average pairing score against parsley, shallot, milk, butter, flour, pepper, cream. Candidates are from the same food group and used in at least 100 recipes.
