Why it works: Beans and spinach match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 365 recipes. Both carry 2-isobutyl-3-methoxypyrazine, which smells green bell pepper, earthy. The science ↓

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, holding the filling inside when cooked.
Butter
Adds richness and flavor to the vegetables and helps keep them moist.
Cooked spinach
Adds moisture and a soft, tender texture to the filling.

The step that matters

Fold the omelet over the vegetables and cook until fully set. Egg proteins set with heat, so cooking too hard or too long makes the omelet tough and rubbery, while underdone egg stays runny inside. Cook gently until the surface is just set.

Swap the cauliflower

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

  1. Asparagusfits better
  2. Chivefits better
  3. Sweet potatofits better
  4. Cauliflowerthe original

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