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

What each ingredient does

Eggs
Set and thicken the cheese mixture as they cook, giving it body.
Cheese
Melts into the sauce to give it richness and a thick, creamy texture.
Strained tomato
Forms the liquid base of the rarebit, adding acidity and body.
Cooked hominy
Provides the firm, starchy base that holds the rarebit mixture.

The step that matters

Stir in the cheese and eggs, cooking until thick while stirring constantly.. Eggs can scramble if the mixture gets too hot or is not stirred, so keeping heat moderate and stirring constantly keeps the sauce smooth while the eggs thicken it.

Swap the onion

How well each one fits the dish's main ingredients (tomato, cheese, egg):

  1. Capsicumfits better
  2. Asparagusfits better
  3. Cucumberfits better
  4. Onionthe original

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