Why it works: Horseradish and lettuce share more aroma than cooks usually use. They rank in the top 2% of all ingredient pairs, and cooks put them together in 79 recipes. Both carry coumarin, which smells sweet, hay. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard boiled eggs
- Provide the whites that hold the filling and the yolks that form its base.
- Butter
- Adds fat, making the mashed yolk filling smooth and rich.
- Cream
- Adds moisture, loosening the yolk mixture so it spreads and fills smoothly.
- Vinegar
- Adds acidity that brightens the rich yolk filling.
The step that matters
Mash the yolks finely. Fine mashing breaks the yolks into small particles so the filling becomes smooth and blends evenly with the butter and cream. Coarse lumps leave a grainy texture that is hard to fix once the other ingredients are added.
Swap the lettuce
How well each one fits the dish's main ingredients (egg, butter, cream, onion, horseradish, pepper, vinegar):
- Mustardfits better
- Chivefits better
- Shallotfits better
- Lettucethe original
Fit is the average pairing score against egg, butter, cream, onion, horseradish, pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes.
