Why it works: Beans and pork are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 2,000 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Boston Baked Beans

Ingredients

Directions

The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

  1. Pick over the beans carefully.

  2. Soak the beans overnight.

  3. Drain the water.

  4. Place the beans in an earthen bean pot.

  5. Add the molasses.

  6. Add the piece of salt pork.

  7. Cover the beans with hot water.

Bake

  1. Bake at 300°F (150°C) for six hours or longer.

  2. Add water as needed to prevent the beans from becoming too dry.

Finish and serve

  1. Bake the beans the day before.

  2. Warm them in the morning.

  3. Boil the beans for about 15 minutes with a little baking soda in the water.

  4. Add more salt to taste.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Beans
Provide the main body and starchy texture of the finished dish.
Molasses
Adds sweetness, dark color and a deep caramel-like flavor during the long bake.
Salt pork
Adds fat and savory flavor that seasons the beans as they cook.
Baking soda (in the method)
Raises the water's alkalinity, which helps the bean skins soften during boiling.

The step that matters

Keep the beans covered with liquid during the long bake. Beans cooked for hours can dry out and scorch, and the starch they need to turn creamy depends on staying moist. Adding hot water as needed keeps them tender and prevents the surface from drying into a tough crust.

Swap the beans

How well each one fits the dish's main ingredients (molasses, pork):

  1. Beansthe original
  2. Peanutfits about as well
  3. Sesamefits less well
  4. Nutsfits less well

Fit is the average pairing score against molasses, pork. Candidates are from the same food group and used in at least 100 recipes.
