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 ↓
Pork and 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 overnight.
The next day, boil the beans with the sliced onion until almost done.
Remove the onions and transfer the beans to a baking dish.
Bake
Place the salt pork in the center of the beans and add some of the boiling water.
Bake at 350°F (175°C) for about 1 hour.
Alternatively, omit the onions, parboil the beans, and place them in a baking pan with molasses and salt pork.
Bake for 2 hours.

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 and become tender and creamy when soaked and cooked.
- Salt pork
- Adds fat and savory flavor that seasons the beans as they bake.
- Molasses
- Adds sweetness and depth of flavor, and helps the sauce darken during baking.
The step that matters
Parboil the beans until almost done. Beans that are undercooked before baking stay firm, because starches soften only slowly in the oven's dry heat. Cooking them nearly through first lets the long bake finish them evenly.
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.
