The flavor team
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
- Beans
- Provide the main body and starch that become tender and creamy when cooked slowly.
- Baking soda
- Raises the water's alkalinity, which helps beans soften when the water is very hard.
The step that matters
Cook slowly and keep the beans covered in water. Gentle simmering keeps the skins intact and the beans tender, while rapid boiling can break them apart. Beans that are exposed to air can dry out and toughen, so adding hot water as needed keeps them evenly cooked.
