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

What each ingredient does

Split peas
Break down into a thick, starchy base that gives the soup its body.
Corned beef
Adds savory, salty meat flavor that carries through the soup.
Butter
Adds richness and a smooth, rounded mouthfeel at the end.

The step that matters

Boil until the peas are soft. Split peas must cook long enough for their starches to fully soften and swell; undercooked peas leave the soup grainy and stop it from thickening properly before straining.

Swap the peas

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

  1. Beansfits better
  2. Peanutfits about as well
  3. Lima beansfits about as well
  4. Peasthe original

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