Why it works: Mustard and lettuce match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,356 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide the whites that hold the filling and the yolks that form the creamy stuffing.
- Melted butter
- Adds fat and moisture so the yolks blend into a smooth, rich paste.
- Ham or tongue
- Adds savory flavor and meaty texture to the yolk filling.
- Mustard
- Adds sharp, tangy flavor that balances the richness of the yolks and butter.
The step that matters
Remove the yolks from the whites. Cooked yolks must be lifted out cleanly so the whites stay intact as cups. Tearing the whites can leave the halves unable to hold the filling.
