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 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Pick and wash the navy beans.
Boil the beans until the skins come off.
Assemble and bake
Grease a pot and fill it with the beans.
Place the onion in the center and lay the bacon strips across the top.
Add the molasses, white sugar, brown sugar, mustard, salt, pepper, and enough hot water to cover the beans.
Bake for at least 6 hours at 300°F (150°C).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Navy beans
- Form the main body of the dish and soften into a tender, creamy texture during baking.
- New orleans molasses
- Adds sweetness, depth and dark colour, and thickens the sauce as it bakes.
- Salt pork
- Adds fat and savory richness that flavors the beans and sauce as they cook.
- Bacon
- Adds smoky, savory fat that renders into the beans and browns on top.
- Onion
- Adds aroma and savory sweetness as it softens in the pot.
The step that matters
Bake for at least 6 hours at 300°F (150°C). Beans need long, gentle heat for their starches to fully soften and absorb liquid. A low, slow bake keeps the skins intact and lets the sauce thicken without scorching. Cutting the time short leaves the beans firm and the sauce thin.
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.
