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 the beans
Wash the desired quantity of beans and soak overnight in enough water to cover them.
In the morning, drain the beans and boil them in fresh water for 15 minutes.
Pour off the water.
Bake
Place the beans in an earthen crock.
Add molasses, mustard, olive oil, salt, and enough water to cover.
Cover the crock with a lid.
Cook slowly in the oven at 300°F (150°C) all day.
Add water occasionally until one hour before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beans
- Provide the starchy, protein-rich body of the dish that softens during long, slow cooking.
- Molasses
- Adds dark sweetness and color, and its sugars brown slowly during the long bake.
- Olive oil
- Adds fat that gives the sauce a richer mouthfeel and carries flavor.
- Mustard
- Adds a sharp, pungent note that balances the sweetness of the molasses.
The step that matters
Add water occasionally until one hour before serving. Beans absorb liquid as they cook and can dry out or scorch during the long bake. Topping up the water keeps them moist and lets the beans soften fully without the sauce burning onto the crock.
Swap the mustard
How well each one fits the dish's main ingredients (beans, molasses, olive):
- Tomatofits better
- Sweet potatofits better
- Welsh onionfits about as well
- Mustardthe original
Fit is the average pairing score against beans, molasses, olive. Candidates are from the same food group and used in at least 100 recipes.
