Why it works: Beans and butter are a kitchen classic. They rank in the top 19% of all ingredient pairs, and cooks put them together in 2,799 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓

Ingredients
Directions
Prepare the beans
Pick over the beans and soak them in cold water overnight.
In the morning, drain and rinse the beans, then place them in fresh water and scald.

Bake
Transfer the mixture to a deep pan and bake for 1.5 hours.

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 turn tender and creamy when simmered.
- Molasses
- Adds sweetness, dark colour and a deep, rich flavour during baking.
- Baking soda
- Raises the pH, helping the bean skins soften and aiding browning.
- Butter
- Adds fat for richer mouthfeel and a smoother, rounder taste.
The step that matters
Boil the beans until fully soft before adding the molasses. Sugar and the acidity of molasses can toughen bean skins and slow softening if added too early. Beans should be fully tender first, so the molasses is stirred in only after the boil.
Swap the beans
How well each one fits the dish's main ingredients (molasses, butter):
- Almondfits better
- Pecansfits better
- Walnutfits about as well
- Beansthe original
Fit is the average pairing score against molasses, butter. Candidates are from the same food group and used in at least 100 recipes.
