Why it works: Lettuce and vinegar are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 2,370 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Dutch Salad
Ingredients
Directions
Prepare
Strip off the outer leaves of the lettuce, cut it in half, and wash it well.
Fry the slice of ham until done, then remove it from the pan.
Make the dressing
In the hot fat, pour in the beaten egg and vinegar, and heat until it thickens.
Cut the lettuce into small pieces and pour the egg and vinegar mixture over it while lukewarm.
Assemble and serve
Place the salad in a deep dish, cut the ham into 1‑inch pieces, and arrange on top.
Let it stand for about five minutes before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Thickens the warm vinegar mixture into a light, creamy coating for the leaves.
- Vinegar
- Adds sharp acidity that balances the richness of the egg and fat.
- Lettuce
- Forms the crisp, leafy base of the salad.
- Ham
- Adds savory, salty flavor and meaty texture.
The step that matters
Heating the egg and vinegar mixture. Egg proteins set as they heat, so the mixture must be heated only until it thickens. Overheating can scramble the egg, leaving lumps instead of a smooth coating.
Swap the lettuce
How well each one fits the dish's main ingredients (ham, egg, vinegar):
- Mustardfits better
- Cucumberfits better
- Shallotfits better
- Lettucethe original
Fit is the average pairing score against ham, egg, vinegar. Candidates are from the same food group and used in at least 100 recipes.
