Why it works: Beans and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 4,733 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Baked Beans
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the beans
Boil the navy beans in 2 quarts of cold water.
When hot, add the baking soda and boil for 1 hour.
Drain and rinse the beans with hot water.
Season and bake
Add the salt, pepper, and granulated sugar.
Transfer to a baking pan and add enough boiling water to cover the beans.
Slice the fresh side meat thinly and lay it on top of the beans.
Bake in a 400°F (200°C) oven for 2 hours or more, turning the meat occasionally to brown it on both sides.

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.

Pepper and sugar barely smell alike, yet cooks put them together in 19,401 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Navy beans
- Form the bulk of the dish, becoming tender and creamy as they cook and bake.
- Baking soda
- Raises the cooking water's alkalinity, helping the beans soften during the long boil.
- Granulated sugar
- Adds sweetness and helps the beans develop a rich, caramelized flavor in the oven.
- Fresh side meat
- Adds fat and savory flavor, and browns on its surface during baking.
The step that matters
Turning the meat while baking. Turning the side meat during the long bake lets both sides brown evenly. Without turning, one side can stay pale or burn while the beans below dry out.
Swap the beans
How well each one fits the dish's main ingredients (pepper, sugar, meat):
- Chestnutfits about as well
- Walnutfits about as well
- Beansthe original
- Sesamefits about as well
Fit is the average pairing score against pepper, sugar, meat. Candidates are from the same food group and used in at least 100 recipes.
