Why it works: Onion and horseradish match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 1,784 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Dutch Sauce
Ingredients
Directions
In a stewpan, combine the sliced onion, horseradish, anchovies, elder vinegar, and second stock.
Boil for 10 minutes, then strain through a fine sieve.
Return the strained mixture to the stewpan.
Make a liaison with the eggs and add to the sauce.
Heat on the fire until it comes to a boil.

Vinegar and egg barely smell alike, yet cooks put them together in 12,922 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the sauce when a liaison is stirred in and heated, giving it body.
- Anchovies
- Add savoury depth that rounds out the sharpness of the vinegar.
- Elder vinegar
- Adds acidity that sharpens the sauce and balances the richness of the eggs.
- Fresh horseradish
- Contributes pungent heat and aroma to the finished sauce.
The step that matters
Adding the liaison. Egg yolks thicken by gently coagulating. If the sauce is too hot when the liaison goes in, or it is allowed to boil hard afterward, the eggs can scramble and turn grainy instead of smoothly thickening the sauce.
Swap the onion
How well each one fits the dish's main ingredients (vinegar, egg, horseradish):
- Mustardfits better
- Cucumberfits better
- Shallotfits better
- Onionthe original
Fit is the average pairing score against vinegar, egg, horseradish. Candidates are from the same food group and used in at least 100 recipes.
