Why it works: Beans and mustard match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 852 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Bean Polenta
Ingredients
Directions
Prepare the beans
Wash the beans and soak them overnight in lukewarm water.
In the morning, drain the water, cover the beans with fresh cold water, and bring to a slow boil.
Boil slowly for one hour, then drain again.
Cover the beans with one quart of fresh boiling water and boil slowly for another hour.
Finish and serve
When done, press the beans through a colander and return to the kettle.
Add the butter, molasses, mustard, salt, pepper, and vinegar; stir and boil for ten minutes.
Serve in a vegetable tureen.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Small white soup beans
- Form the bulk of the dish; pressing them softens them into a smooth, thick body.
- Butter
- Adds fat and richness, giving the mash a smoother, rounder mouthfeel.
- Molasses
- Adds sweetness and dark, caramel-like depth of flavour.
- Vinegar
- Adds acidity that brightens the sweet molasses and balances the richness.
- French mustard
- Adds sharp, pungent flavour that cuts through the sweetness.
The step that matters
Boil the beans in two stages with a drain in between. Fresh water replaces the liquid that carries off bitter compounds and some gas-causing sugars, and a full second boil softens the beans enough to press smoothly. Skipping the drain or cutting the second boil leaves the mash grainy and harsher in flavour.
