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 says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Pick the beans and soak them overnight in water.
Assemble
In a bean jar, place half the pork and the onion.
Pour in half the beans, then add the remaining pork and the rest of the beans.
Stir in the molasses, mustard, and sugar.
Cover with boiling water.
Bake
Bake at 350°F (175°C) for 6 to 7 hours.
Keep the beans covered with water until the last hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beans
- Form the main body of the dish and become tender and creamy during the long bake.
- Salt pork
- Renders fat and salty, savory flavor into the beans as it cooks.
- Molasses
- Adds sweetness and a dark color to the sauce.
- Mustard
- Adds a sharp tang that balances the sweetness.
- Sugar
- Adds sweetness and helps the sauce brown as it bakes.
- Onion
- Adds savory aroma and flavor to the beans.
The step that matters
Keep the beans covered with water until the last hour. Beans need enough liquid to cook evenly and absorb flavor over a long bake. If they dry out and are exposed to the oven air, the outer beans can toughen and the sauce can scorch or thicken unevenly.
Swap the onion
How well each one fits the dish's main ingredients (beans, pork, molasses, mustard, sugar):
- Lettucefits better
- Sweet potatofits better
- Beetrootfits better
- Onionthe original
Fit is the average pairing score against beans, pork, molasses, mustard, sugar. Candidates are from the same food group and used in at least 100 recipes.
