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 ↓
Deviled Eggs
Ingredients

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 are mashed into it.
- Mayonnaise
- Adds moisture and creaminess to the mashed yolks.
- Melted butter or olive oil
- Adds fat, making the yolk filling smoother and richer.
- Mustard
- Adds sharp acidity that balances the richness of the yolks.
The step that matters
Cook the eggs for 20 minutes. Overcooking makes the yolks dry and chalky and can leave a grey-green ring around them. Cooling the eggs quickly in cold water helps stop the cooking and makes the shells easier to peel.
Swap the lettuce
The recipe marks lettuce as optional. How well each one fits the dish's main ingredients (egg, butter, pepper, mustard, celery):
- Horseradishfits about as well
- Chivefits about as well
- Lettucethe original
- Spinachfits about as well
Fit is the average pairing score against egg, butter, pepper, mustard, celery. Candidates are from the same food group and used in at least 100 recipes.
