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

  1. Place the beans in a bean jar, parboil them, then drain the water.

  2. Add the smoked ham, salt, pepper, ground mustard, and Orleans molasses.

  3. Cover the mixture with plenty of water.

Bake

  1. Bake in a slow oven at 300°F (150°C) for 24 to 36 hours.

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

What each ingredient does

Small white beans
Provides the starchy bulk that softens into a creamy, thick base.
Smoked ham
Adds smoky, savory flavor and fat that enriches the beans as they cook.
Orleans molasses
Adds sweetness and dark color, deepening the flavor of the baked beans.

The step that matters

Keeping the beans covered with water during the long bake. Beans need a long, slow cook to soften fully and become creamy. If the liquid drops below the beans, they dry out, scorch, and cook unevenly. Low, steady heat keeps the skins from splitting.

Swap the beans

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

  1. Beansthe original
  2. Lentilsfits about as well
  3. Black-eyed peafits less well
  4. Chestnutfits less well

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