Why it works: Potato and onion are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Endive Salad
Ingredients
Directions
Prepare the endive
Remove the dark leaves from the endive and cut the rest into small pieces, splitting the stalk.
Soak the endive in salt water for several hours to reduce bitterness.
Make the salad
Boil the potatoes until tender, then drain and mash them with a fork.
Mix in salt, pepper, chopped celery, chopped onion, and the soaked endive.
Add mayonnaise to the mixture and combine well.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Endive
- Its natural bitterness is reduced by soaking in salt water, giving a milder salad.
- Potatoes
- Mashed when cooked, they form the creamy base that holds the salad together.
- Mayonnaise
- Adds fat and moisture, binding the mashed potato and vegetables into a creamy texture.
- Onion
- Adds sharp, aromatic flavour that brightens the rich mayonnaise and potato.
The step that matters
Soaking the endive in salt water. Soaking for several hours draws out and dilutes the bitter compounds in endive. Skipping or shortening it leaves the salad noticeably bitter.
Swap the endive
How well each one fits the dish's main ingredients (potato, pepper, celery, onion):
- Carrotfits better
- Chivefits better
