Why it works: Onion and lettuce match in chemistry and in kitchens. They rank in the top 8% of all ingredient pairs, and cooks put them together in 3,562 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Egg and Lettuce Salad
Ingredients
Directions
Prepare the eggs

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 structure of the dish; the whites hold the yolk filling and the yolks form its base.
- Melted butter
- Adds fat and richness, giving the mashed yolk filling a smoother, creamier texture.
- Salad dressing
- Adds moisture and tang, binding the mashed yolks into a spreadable filling.
- Minced ham
- Adds savory flavor and a little texture to the yolk filling.
The step that matters
Mashing the yolks into the filling. Yolks mashed while still warm or unevenly blended can leave lumps or dry patches. Adding the butter and dressing gradually and mashing thoroughly gives a smooth, cohesive filling that holds its shape when piped or spooned back into the whites.
