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 the beans

  1. Soak the navy beans overnight in cold water.

  2. Wash the beans thoroughly.

  3. Place the beans in fresh cold water.

  4. Parboil the beans until slightly tender, being careful not to break them.

Prepare the pork

  1. Cook the pork in a little water for 15–20 minutes.

  2. Remove the pork and scrape the rind.

  3. Cut the rind into narrow strips.

Assemble and bake

  1. Place the beans in a bean pot.

  2. Bury the pork in the beans, leaving the rind exposed.

  3. Mix the salt, molasses, and mustard.

  4. Add one cup of water to the mixture.

  5. Pour the mixture over the beans.

  6. Add the liquid from boiling the pork to season the beans.

  7. Bake the beans in a 350°F (175°C) oven for 6–7 hours, keeping them covered with water.

  8. In the last hour, raise the pork to the top of the beans to crisp the rind.

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

What each ingredient does

Navy beans
Provide the bulk and starchy body that becomes tender during the long slow bake.
Pork
Adds savoury fat and flavour to the beans, and the rind crisps at the surface.
Molasses
Adds sweetness and dark colour, and deepens the flavour of the baked beans.
Mustard
Adds a sharp, pungent note that balances the sweetness of the molasses.

The step that matters

Raising the pork to crisp the rind. Raising the pork only in the last hour lets the rind brown and crisp by dry heat, while the beans below stay moist. Leaving it submerged the whole time would leave the rind soft.
