Why it works: Butter and potato are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 6,456 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Dutch Lettuce
Ingredients
Directions
Prepare
Wash lettuce, cut finely, and drain all water off. Place in a dish and add onions, sliced boiled eggs, salt, and sugar.
Mash the hot potatoes and place them on top of the lettuce mixture.
Dress and serve
Heat the vinegar until it melts the butter, or alternatively fry 3 or 4 slices of bacon, use the grease instead of butter, and pour the hot mixture over the lettuce.
Serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Vinegar
- Adds sharpness that balances the sweetness and richness of the dressing.
- Butter
- Adds fat and richness to the warm dressing.
- Bacon
- Its rendered grease adds fat and savory flavor to the dressing.
- Boiled potatoes
- Add starch and body to the salad when mashed while hot.
The step that matters
Pour the dressing over the lettuce while it is hot. Hot vinegar and fat wilt the cut lettuce slightly and spread flavor evenly. If the dressing cools first, the leaves stay stiff and the flavor sits on top instead of coating them.
Swap the potato
How well each one fits the dish's main ingredients (butter, vinegar, egg):
- Cucumberfits better
- Shallotfits better
- Mustardfits better
- Potatothe original
Fit is the average pairing score against butter, vinegar, egg. Candidates are from the same food group and used in at least 100 recipes.
