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. Clean the beans and soak them overnight.

  2. Rinse and parboil the beans in plenty of water with the baking soda and pork, scored on the rind.

  3. After boiling, reduce the heat and cook for 15 minutes.

Bake

  1. Rinse the beans again and place half of them in a bean pot, then add the pork, rind side up.

  2. Add the remaining beans, seasoning, and enough water to cover.

  3. Cook slowly in the oven at 300°F (150°C) for ten hours, adding water as needed.

  4. Ensure every bean is whole when serving.

  5. Add sugar if desired for sweetness.

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

What each ingredient does

Beans
Form the bulk of the dish and become tender and creamy during the long slow cook.
Pork
Adds savory fat and flavor to the beans as it cooks slowly with them.
Baking soda
Raises the pH of the cooking water, helping the beans soften during parboiling.
Molasses
Adds sweetness, dark color, and a deep caramel-like flavor during the long bake.

The step that matters

Keep the beans covered with water during the long bake. Beans that dry out at the surface can toughen and split unevenly, so adding water as needed keeps them moist and evenly tender over the many hours in the oven.
