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 ↓
Boston Baked Beans
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the beans
Cover the beans with water and bring the covered beans to a boil.
Drain the water.
Cover the beans again with water and add a pinch of baking soda.
Simmer for 3 to 4 hours, or until you can easily crush a bean between your fingers.
Season and bake
Place the beans in a bean pot.
Season the beans with salt and pepper.
Add the molasses and sugar if desired.
Add the pickled pork.
Bake the beans in a 300°F (150°C) oven for 6 hours.
Keep the beans covered with water until the last hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Dried beans
- Form the main body of the dish, becoming tender and creamy during long cooking.
- New orleans molasses
- Adds sweetness, deep color and a rich flavor as it caramelizes slowly in the oven.
- Pickled pork
- Contributes salty, savory fat that flavors the beans throughout the long bake.
- Baking soda
- Raises the pot's alkalinity, helping beans soften more quickly during simmering.
The step that matters
Keep the beans covered with water until the last hour. Beans baked in a dry pot can dry out, toughen and scorch on top. Keeping them submerged keeps them moist while the starches gelatinize and the sauce thickens.
Swap the beans
How well each one fits the dish's main ingredients (pepper, molasses, sugar, pork):
- Beansthe original
- Chestnutfits about as well
- Sesamefits less well
- Peanutfits less well
Fit is the average pairing score against pepper, molasses, sugar, pork. Candidates are from the same food group and used in at least 100 recipes.
