Why it works: Beans and olive match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 3,470 recipes. Both carry trans,trans-2,4-nonadienal, which smells fatty, green. The science ↓
Haricot Bean Omelet
Ingredients
Directions
The book says “a moderately hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the beans
Soak the haricot beans in cold water for several hours.
Boil the beans in fresh water until soft.
Mash the beans with the milk and strain through a fine colander.
Make the omelet
Mix in the bread crumbs, chopped parsley, beaten eggs, olive oil, salt, and pepper.
Pour the mixture into a buttered dish.
Bake and serve
Bake for about 1 hour at 350°F (175°C).
Serve with brown sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Haricot beans
- Form the bulk of the omelet and give it a soft, starchy body.
- Eggs
- Set during baking to bind the mixture into a firm, sliceable omelet.
- Bread crumbs
- Absorb liquid and add body so the omelet holds together.
- Milk
- Adds moisture and softness, loosening the mashed beans for mixing.
- Olive oil
- Adds fat, which keeps the omelet moist and tender as it bakes.
The step that matters
Boil the beans until soft. Beans that are not fully tender stay grainy and resist mashing, so the omelet ends up with lumps and uneven texture. Soaking first helps them cook through evenly.
Swap the beans
How well each one fits the dish's main ingredients (bread, egg, milk, olive, pepper):
- Peasfits about as well
- Walnutfits about as well
- Beansthe original
- Chickpeafits about as well
Fit is the average pairing score against bread, egg, milk, olive, pepper. Candidates are from the same food group and used in at least 100 recipes.
