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 ↓
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. 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 the beans
Soak the beans overnight in water.
Drain and rinse the beans, then place them in a pot with 4 cups of water.
Bring to a boil, then reduce heat and simmer for 1 hour.
Bake
Preheat the oven to 350°F (175°C).
In a baking dish, combine the cooked beans, onion, molasses, brown sugar, mustard, salt, and pepper.
Cover and bake for 2 to 3 hours, adding water as needed to keep the beans moist.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Navy beans
- Provide the main body and starchy texture that holds the baked beans together.
- Molasses
- Adds dark sweetness, color, and a deep flavor that defines the baked beans.
- Brown sugar
- Adds sweetness and helps the sauce caramelize and thicken during slow baking.
- Onion
- Adds savory aroma and depth as it softens and flavors the sauce.
- Mustard
- Adds a sharp tang that balances the sweetness of the molasses and sugar.
The step that matters
Keeping the beans moist while baking. Beans can dry out and scorch during the long covered bake. Adding water as needed keeps the beans tender and the sauce from drying into a crust.
