Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Haricot beans
Provide the main body and thickening starch once softened and pureed through the sieve.
Bone stock
Supplies the savory liquid base and deep meaty flavor for the soup.
Onions
Add sweetness and aromatic depth as they cook down into the broth.
Milk
Adds creaminess and softens the soup's flavor and texture.
Butter
Adds richness and a silky mouthfeel when stirred in at the end.

The step that matters

Rub the mixture through a sieve. Pressing the cooked beans and onions through a sieve breaks down their starch and fibre, creating a smooth, thick texture. Skipping or rushing this step leaves the soup grainy and thin.

Swap the beans

How well each one fits the dish's main ingredients (onion, milk, pepper, butter):
