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 ↓
Pork and Beans
Ingredients
Directions
The book says “a very slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare and simmer
Soak the beans overnight if possible.
In a pot, combine the beans, salt pork, onion, pepper, and coarse sea salt.
Add enough cold water to cover the ingredients.
Heat the pot slowly on the side of the range for at least an hour.
Bring to a boil, then reduce to a very slow boil for 3 to 6 hours until the beans are tender.
Occasionally add a little cold water to ensure even cooking.
Once tender, drain the liquid into a bowl.
Bake and serve
Transfer the beans to a bake dish, add the molasses, and fill to the level of the beans with the reserved liquid.
Bake in a slow oven at 300°F (150°C) for about 2 hours until the top is browned and the beans are creamy.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White beans
- Provide the main body and creamy texture once cooked slowly until tender.
- Salt pork
- Adds fat and savory flavor that seasons the beans during long simmering.
- Molasses
- Adds sweetness and deep color, helping the top brown in the oven.
- Onion
- Adds aroma and savory sweetness as it softens during cooking.
The step that matters
Long, very slow simmer. Beans need gentle, prolonged heat to soften evenly; a hard boil can break the skins and leave some beans mushy while others stay firm. Adding a little water keeps the beans submerged so they cook evenly.
