Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Ha-ricot Bean Omelet
Ingredients
Directions
The book says “a rather brisk oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the beans
Pick and wash the beans, then soak them overnight.
Boil the beans until soft.
Make the mixture
Mash the beans with the butter.
Add the bread crumbs, chopped parsley, beaten egg, and milk; season with pepper and salt.
Bake and serve
Put the mixture into a buttered dish and bake for 1 hour at 400°F (200°C).
Serve with brown or onion 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, mashable body.
- Bread crumbs
- Absorb moisture and add body so the mixture holds together when baked.
- Egg
- Binds the mixture and sets during baking to hold its shape.
- Butter
- Adds richness and fat, softening the mashed beans and adding flavor.
- Milk
- Adds moisture and softness to the mixture while it bakes.
The step that matters
Mash the beans with the butter. Beans must be soft enough to mash smoothly; under-cooked beans stay grainy and do not bind well with the other ingredients, leaving the omelet crumbly.
Swap the beans
How well each one fits the dish's main ingredients (bread, egg, butter, parsley, milk, pepper):

- Chestnutfits about as well
Fit is the average pairing score against bread, egg, butter, parsley, milk, pepper. Candidates are from the same food group and used in at least 100 recipes.
