Why it works: Mustard and onion match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 9,259 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Soak the kidney beans in cold water overnight, then drain.
Place the beans in a bean pot.
Assemble
Mix the molasses, dry mustard, brown sugar, and salt together.
Pour the mixture over the beans and add the onion.
Place the fatty beef on top.
Bake
Bake in a slow oven at 300°F (150°C) for 6 hours, adding a little water as needed.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Kidney beans
- Provide the main body and starchy texture of the dish.
- Molasses
- Adds dark color, sweetness and a deep, rich flavor during the long bake.
- Brown sugar
- Adds sweetness and helps the sauce caramelize and thicken slightly.
- Very fatty beef
- Renders fat and flavor into the beans as they bake slowly.
- Onion
- Adds savory aroma and depth that mellows during baking.
The step that matters
Baking in a slow oven with added water. Beans must cook long enough at low heat to become fully tender and to let the sauce thicken. Sugars can scorch if the heat is too high or the liquid runs out, so water is added as needed to keep the beans moist.
Swap the kidney beans
How well each one fits the dish's main ingredients (molasses, mustard, sugar, onion, beef):
- Beansfits better
- Sesamefits better
- Chestnutfits better
- Kidney beansthe original
Fit is the average pairing score against molasses, mustard, sugar, onion, beef. Candidates are from the same food group and used in at least 100 recipes.
