Why it works: Celery and lettuce match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 2,033 recipes. Both carry nonanal, which smells fat, citrus. The science ↓
Egg Salad
Ingredients
Directions
Prepare the eggs
Peel the hard-boiled eggs carefully.
Cut a small piece off the end of the egg whites so they can stand upright.
Cut the eggs in half and remove the yolks.
Make the filling
Press the yolks through a potato masher until smooth.
Mix the yolks with melted butter, celery extract, salad dressing, salt, pepper, and vinegar.
Fill and serve
Refill the egg whites with the yolk mixture.
Serve the filled eggs on lettuce leaves.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide the white shells that hold the filling and the yolks that form the creamy base.
- Melted butter
- Adds richness and a smooth, silky texture to the yolk mixture.
- Salad dressing
- Adds moisture, tang, and flavor that bind the yolks into a spreadable filling.
The step that matters
Press the yolks through a potato masher until smooth. Yolks that are left lumpy stay grainy and dry, while thoroughly mashed yolks blend with the butter and dressing into an even, creamy filling.
Swap the lettuce
How well each one fits the dish's main ingredients (egg, butter, celery, pepper, vinegar):
- Capsicumfits better
- Mustardfits better
- Carrotfits about as well
- Lettucethe original
Fit is the average pairing score against egg, butter, celery, pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes.
