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

What each ingredient does

Eggs
Set into the structure of the omelet as they cook, forming its body.
Lemon juice
Adds a bright acidity that lifts the flavour of the eggs.

The step that matters

Cook until firm. Eggs turn from liquid to set as their proteins coagulate with heat. Cooking gently until just firm keeps the omelet tender, while overcooking makes it dry and rubbery.

Swap the lemon

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

  1. Lemonthe original
  2. Vanillafits about as well
  3. Coconutfits about as well
  4. Raspberryfits less well

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