Why it works: Lentils and pepper work together. They rank in the top 13% of all ingredient pairs, and cooks put them together in 812 recipes. Both carry coumarin, which smells sweet, hay. The science ↓

Egg and pepper barely smell alike, yet cooks put them together in 50,580 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
- Bind the lentils and set into a firm, cohesive omelette when cooked.
- Boiled lentils
- Provide the bulk and body of the omelette, giving it a hearty, protein-rich texture.
- Butter
- Adds richness and helps prevent sticking while the omelette cooks in the skillet.
The step that matters
Cook until set, then fold. Cooking over medium heat lets the egg coagulate gently so it sets without turning rubbery or browning too fast. Folding only once the base is firm keeps the omelette intact.
Swap the lentils
How well each one fits the dish's main ingredients (egg, pepper, butter):
- Walnutfits better
- Almondfits better
- Peasfits better
- Lentilsthe original
Fit is the average pairing score against egg, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
