Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓

Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the beans
Wash the beans well and remove any bad ones.
Soak the beans in water with baking soda overnight.
In the morning, boil the beans in a saucepan for 2 hours.
Make the sauce
In a bowl, rub together the butter and flour.
Add the butter‑flour mixture to the milk along with salt and pepper.
Assemble and bake
Butter a pudding dish and layer in the beans and milk mixture alternately.
Top with bread crumbs and a few bits of butter.
Bake in a 350°F (175°C) oven for 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White beans
- Form the bulk of the dish and hold their shape while baking in the sauce.
- Baking soda
- Softens the bean skins during soaking so the beans cook more evenly.
- Milk
- Forms the liquid base that bakes into a creamy, set custard around the beans.
- Butter
- Adds richness and fat, and the topping butter helps the crumbs brown.
- All-purpose flour
- Thickens the milk mixture so it becomes a smooth, creamy sauce.
- Bread crumbs
- Form a crisp, golden topping through browning in the oven.
The step that matters
Adding the butter-flour mixture to the milk. Flour must be fully blended into the butter and mixed evenly into the milk, otherwise it can clump and leave floury lumps instead of a smooth, thickened sauce.
Swap the beans
How well each one fits the dish's main ingredients (milk, butter, flour, pepper, bread):
- Almondfits better
- Chestnutfits about as well
- Beansthe original
- Walnutfits about as well
Fit is the average pairing score against milk, butter, flour, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
