Why it works: Beans and onion match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 5,242 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Baked Beans
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the beans
Soak the beans in cold water overnight.
In the morning, parboil the beans and then drain them.
Assemble and bake
Cover the bottom of a bean pot with slices of salt pork.
Add the quartered onion and pour in the beans.
Place a piece of pork on top and add the molasses.
Bake in a preheated oven at 350°F (175°C), covering with water.
Add more water as needed and salt to taste when half done.
Mustard may be added if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Dried beans
- Form the bulk of the dish, becoming tender and creamy as they cook slowly.
- Salt pork
- Adds fat and savory flavor that seasons the beans as it renders during baking.
- Molasses
- Adds sweetness and deep color to the sauce as it bakes.
- Onion
- Contributes aromatic flavor that mellows into the beans during long baking.
The step that matters
Keep the beans covered with water during baking. Dried beans need constant moisture to cook evenly and become tender; if they are exposed to air they can dry out, toughen, and scorch on top.
Swap the onion
How well each one fits the dish's main ingredients (beans, pork, molasses):
- Potatofits better
- Mustardfits better
- Sweet potatofits better
- Onionthe original
Fit is the average pairing score against beans, pork, molasses. Candidates are from the same food group and used in at least 100 recipes.
