Why it works: Beans and mustard match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 852 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 the beans

  1. Soak the beans overnight in cold water.

  2. Drain the beans and cover them with fresh water.

  3. Cook just below boiling until the skins burst when blown upon.

Bake

  1. Put the beans, onion, salt pork (or vegetable oil), sorghum, and mustard into a bean pot or casserole.

  2. Cover with water and bake slowly at 300°F (150°C) for 6 to 8 hours, adding water as needed.

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 and turn tender and creamy during the long slow bake.
Salt pork
Adds fat and savory richness that carries through the beans as they bake.
Sorghum
Provides sweetness and a dark, molasses-like flavor as it cooks down.
Onion
Adds aromatic savory depth that mellows during the slow bake.

The step that matters

Cook just below boiling until the skins burst when blown upon. Boiling vigorously can break the beans apart and leave them mushy, while gentle heat softens them evenly. Keeping the water just under a boil lets the skins loosen without splitting the beans.

Swap the onion

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

  1. Lettucefits better
  2. Welsh onionfits better
  3. Shallotfits better
  4. Onionthe original

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