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 ↓
Boiled Beans and Peas
Ingredients
Directions
Soak and boil
Soak the beans or peas in soft water for 12 to 24 hours.
Boil the soaked beans or peas in soft water for 2 to 3 hours.
Treat hard water
If using hard water, add ½ teaspoon baking soda per quart of beans, pour off the water after 30 minutes, and replace with fresh boiling water.
Season and serve
Once soft, season with salt, pepper, and fat.
For added flavor, serve with tomato sauce or fruit.
Discard the first boiling water and replenish the second water sparingly.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Dried beans or peas
- Provide the main body and starch that soften into a tender, thick dish.
- Baking soda
- Raises the water's alkalinity, helping beans soften when the water is hard.
- Fat (butter or pork)
- Adds richness and a smoother mouthfeel to the cooked beans.
The step that matters
Using baking soda with hard water. Minerals in hard water toughen bean skins and slow softening. Baking soda raises the water's alkalinity, which helps the beans soften. It is needed only with hard water, so measure it carefully.
