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):
- Capsicumfits better
- Asparagusfits better
- Chivefits better
- 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.
