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 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Soak the beans overnight in water.
Drain and place beans in a pot with fresh water.
Simmer
Add molasses, brown sugar, salt, pepper, and onion.
Bring to a boil.
Reduce heat and simmer for 2 hours.
Stir in the bacon.
Bake
Bake at 300°F (150°C) 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
- Provide the main body and starchy texture of the finished dish.
- Molasses
- Adds dark color, deep sweetness, and a rich flavor during long cooking.
- Brown sugar
- Contributes sweetness and helps deepen the color and caramel notes.
- Bacon
- Adds fat and smoky, savory flavor that seasons the beans as it renders.
- Onion
- Adds savory aromatic flavor that mellows during simmering and baking.
The step that matters
Simmer until the beans are tender. Beans must be fully softened before baking, since the sugar and molasses added with the acid-free liquid can slow softening and the oven time alone will not fully cook them.
Swap the onion
How well each one fits the dish's main ingredients (beans, molasses, sugar, pepper):
- Capsicumfits better
- Sweet potatofits better
- Mustardfits better
- Onionthe original
Fit is the average pairing score against beans, molasses, sugar, pepper. Candidates are from the same food group and used in at least 100 recipes.
