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 with Tomato
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the beans
Soak the beans overnight.
In the morning, boil the beans with a pinch of baking soda, then drain the water and cover the beans with cold water.
Cook and bake
Add the bacon and molasses, then cook until tender.
Transfer the beans to a baking dish and bake at 300°F (150°C) for 1 hour.
In a skillet, brown the onion in butter.
Add the browned onion, tomatoes, chile, salt, and cayenne pepper to the beans.
As it cooks down, add more sauce and a little water if necessary until the beans are done.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beans
- Form the bulk of the dish and absorb the sauce as they cook down and soften.
- Molasses
- Adds sweetness and a dark, rich color to the sauce.
- Bacon
- Adds smoky, savory fat that flavors the beans as they cook.
- Tomatoes
- Contribute acidity and body to the sauce, which thickens as it reduces.
- Onion
- Browning in butter first builds sweet, savory depth for the sauce.
- Butter
- Adds fat and helps the onion brown, deepening its flavor.
The step that matters
Boil the beans with baking soda, then drain and re-cover with cold water. Baking soda raises the pH of the cooking water, which helps beans soften. Discarding that water removes compounds that cause gas and off flavors, so the beans cook evenly and tenderly.
