Why it works: Lentils and flour match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 255 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ingredients
Directions
Prepare the macaroni
Put macaroni in cold water to cover, add salt, and boil until soft.
Drain the macaroni and cut into half-inch lengths.
Make the lentil mixture
In a pot, combine chopped onion, lentils, and cold water.
Boil the mixture until soft.
Add butter, sweet herbs, pepper, and salt to the lentil mixture. Mix well.
Stir in the egg and cook until firm without boiling.
Gently mix the macaroni with the lentil mixture.
Shape, fry and serve
Divide the mixture into portions.
Form each portion into a cutlet.
Coat the cutlets in flour.
Fry the cutlets in boiling fat until golden.
Serve the cutlets arranged in a circle with boiled Brussels sprouts in the center.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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
- Macaroni
- Provides the bulk and starchy body that holds the cutlet together.
- Lentils
- Softened and mashed, they give the cutlets their main texture and moisture.
- Egg
- Sets when cooked, binding the macaroni and lentils into a firm cutlet.
- Spanish onion
- Adds savoury depth and moisture to the lentil base as it softens.
- Butter
- Adds richness and fat, contributing flavour and a softer mouthfeel.
The step that matters
Stir in the egg and cook until firm without boiling. Egg proteins set with gentle heat; if the mixture boils or overcooks, the egg can curdle and toughen, making the cutlets crumbly or rubbery rather than cohesive.
Swap the brussels sprouts
How well each one fits the dish's main ingredients (onion, lentils, butter, pepper, egg, flour):
- Chivefits better
- Leekfits better
- Spinachfits better
- Brussels sproutsthe original
Fit is the average pairing score against onion, lentils, butter, pepper, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
