Onion and cream barely smell alike, yet cooks put them together in 10,827 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Eggs
Set into the body of the omelet as their proteins coagulate with gentle heat.
Cream
Adds moisture and a softer, more tender texture to the set eggs.
Onion
Adds savory aroma and sweetness as it softens during cooking.

The step that matters

Cook gently in the double boiler or steamer. Egg proteins set at moderate heat. Too much heat or too long a cook makes eggs tough, rubbery and watery, so keep the water at a gentle simmer and watch the custard-like set.

Swap the lettuce

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

  1. Spinachfits better
  2. Potatofits better
  3. Chivefits better
  4. Lettucethe original

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