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 ↓

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.
Simmer
Add sugar, salt, mustard, tomato sauce, and water to the pot.
Bring to a boil, then reduce heat and simmer for 2 hours.
Bake and serve
Transfer to a baking dish and bake at 350°F (175°C) for 1 hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Dried beans
- Provide the main body and starchy texture of the dish.
- Tomato sauce
- Adds acidity and flavour, and contributes to the sauce's moisture.
- Sugar
- Adds sweetness that balances the acidity of the tomato sauce.
- Mustard
- Adds sharp aroma and a tangy flavour to the sauce.
The step that matters
Simmer the beans until tender. Dried beans must be cooked long enough to soften fully before baking. Beans not simmered thoroughly stay firm, and adding salt and acid to the pot early can slow softening, so the simmer time matters for texture.
Swap the tomato
How well each one fits the dish's main ingredients (beans, sugar, mustard, sauce):
- Horseradishfits better
- Lettucefits better
- Welsh onionfits better
- Tomatothe original
Fit is the average pairing score against beans, sugar, mustard, sauce. Candidates are from the same food group and used in at least 100 recipes.
