Why it works: Potato and beans match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 655 recipes. Both carry 2-isobutyl-3-methoxypyrazine, which smells green bell pepper, earthy. The science ↓
Fish Salad
Ingredients
Directions
Prepare the vegetables
Bake the potatoes, then peel them and let them cool.
Cook the haricot beans as usual.
Boil the eggs until hard.
Slice the cooled potatoes into a bowl or glass dish and mix them with the beans.
Prepare the fish
Remove the skin, bones, and fillets from the sardines and anchovies.
Mix the sardines and anchovies with the vegetables.
Make the dressing and serve
In a mortar, pound the yolks of two eggs with ¼ teaspoon of mustard and a pinch of salt.
Add enough oil to create a smooth cream.
Mix in one-third the quantity of vinegar.
Pour the dressing over the vegetables and stir to combine.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the starchy bulk that holds the salad together and absorbs the dressing.
- Eggs
- Egg yolks emulsify with oil and mustard to form a smooth, creamy dressing.
- Haricot beans
- Add body and substance, giving the salad a firm, filling texture.
- Sardines
- Contribute rich, savoury fish flavour and oils to the salad.
- Anchovies
- Add concentrated salty, savoury depth that seasons the whole salad.
- Vinegar
- Adds acidity that brightens the dressing and cuts the richness of the oil and fish.
The step that matters
Adding the oil to the yolks. Oil must be added slowly while pounding the yolks so they emulsify into a smooth cream; adding it too fast causes the dressing to split and turn greasy.
Swap the beans
How well each one fits the dish's main ingredients (potato, egg, vinegar):
- Sesamefits better
- Peanutfits about as well
- Beansthe original
- Peasfits about as well
Fit is the average pairing score against potato, egg, vinegar. Candidates are from the same food group and used in at least 100 recipes.
