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

What each ingredient does

Eggs
Set into a soft, custard-like texture as the proteins coagulate with gentle heat.
Tomato juice
Adds moisture and a mild acidity and flavour to the egg mixture.

The step that matters

Steam for 10 minutes in gently boiling water. Egg proteins set at moderate heat, so steaming gently gives a tender custard. Too vigorous a boil or too long a steam can make the eggs rubbery, pocked, or watery.

Swap the tomato

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

  1. Capsicumfits better
  2. Asparagusfits better
  3. Chivefits better
  4. Tomatothe original

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