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

Oven, in the book's wordsA moderate oven

Ingredients

Directions

The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Soak the beans in water overnight.

  2. In the morning, drain and sort the beans, then place them in a large bean pot.

  3. Add the washed pork on top of the beans.

Season and bake

  1. Dissolve the salt and molasses in a small amount of water, and add mustard if desired.

  2. Pour the mixture over the beans, adding enough water to cover them.

  3. Bake in a moderate oven at 350°F (175°C) all day if serving in the evening, or cover and leave in the oven overnight for breakfast.

  4. Add water as needed throughout the day.

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

What each ingredient does

Small pea beans
Form the bulk of the dish and turn tender and creamy during the long, slow bake.
Molasses
Adds sweetness and a deep brown colour to the beans and sauce.
Salt pork
Adds fat and savoury flavour that seasons the beans as it renders during baking.
Coarse sea salt
Seasons the beans and balances the sweetness of the molasses.

The step that matters

Keep the beans covered with water. Beans that dry out at the top can scorch and toughen while the long, slow bake continues, so water must be added as needed throughout the day.

Swap the mustard

The recipe marks mustard as optional. How well each one fits the dish's main ingredients (beans, pork, molasses):

  1. Potatofits about as well
  2. Mustardthe original
  3. Sweet potatofits about as well
  4. Tomatofits about as well

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