Why it works: Beans and onion match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 5,242 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Baked Beans
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the beans
Pick over the beans carefully, wash, and soak them in soft water.
Bring the beans to a boil in the same water.
Simmer
Simmer until tender and the fluid is nearly absorbed, adding more water if necessary.
Bake
Pour the beans into a bean pot or round pan.
Cover the top with cooking oil.
Cover the top with the whole onion.
Bake at 400°F (200°C) for about an hour.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

What each ingredient does
- Dried beans
- Form the body of the dish, softening as they absorb water and cook into a tender texture.
- Cooking oil
- Adds fat and helps the top surface brown in the oven.
- Onion
- Adds aroma and gentle sweetness as it cooks slowly in the oven.
The step that matters
Simmer until tender. Dried beans must soften fully before baking, because the oven cannot finish cooking firm beans well. Adding water as needed keeps the beans covered so they cook evenly and do not dry out or scorch.
