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 starch that thicken the soup when cooked and sieved.
Dripping
Adds fat, which carries flavour and gives the soup a richer mouthfeel.
Baking soda
Raises the pH, which helps the beans soften during long boiling.
Milk
Added at the end to adjust thickness and add creaminess.

The step that matters

Rub the mixture through a sieve. Pressing the cooked beans through a sieve breaks down their starchy cell walls, creating a smooth texture. Skipping or rushing this step leaves the soup grainy.

Swap the beans

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

  1. Cocoafits about as well
  2. Beansthe original
  3. Walnutfits about as well
  4. Soybeanfits about as well

Fit is the average pairing score against pepper, milk. Candidates are from the same food group and used in at least 100 recipes.
