Why it works: Beans and tomato match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 2,713 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.
Prepare the beans
Soak the navy beans in water overnight.
Drain the beans.
Cover the beans with fresh water.
Add the baking soda and the salt pork.
Boil the beans for 30 minutes.
Drain the beans.
Place the beans in a small roasting pan.
Make the sauce
Combine the tomatoes and chopped onion in a pot.
Boil the mixture for 20 minutes.
Strain the mixture.
Bake and serve
Add the strained mixture to the beans along with the molasses, syrup, sugar, and mustard.
Mix everything together.
Bake for 1.5 hours at 350°F (175°C).

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 of the finished dish.
- Salt pork
- Adds fat and savory depth that carries through the long bake.
- Tomatoes
- Add acidity and body to the sauce that coats the beans.
- Molasses
- Adds sweetness, dark color, and a deep, caramel-like flavor during baking.
- Syrup
- Adds sweetness and helps the sauce thicken and brown in the oven.
- Baking soda
- Raises the pH of the soaking water, helping the bean skins soften.
The step that matters
Boil the beans until tender before adding the sauce. Sugars and acids in the tomatoes and molasses toughen bean skins and slow softening. Beans that are not fully tender after the initial boil will stay firm even after the long bake.
Swap the onion
How well each one fits the dish's main ingredients (beans, pork, tomato, molasses, syrup, sugar, mustard):
- Sweet potatofits better
- Capsicumfits better
- Lettucefits better
- Onionthe original
Fit is the average pairing score against beans, pork, tomato, molasses, syrup, sugar, mustard. Candidates are from the same food group and used in at least 100 recipes.
