Why it works: Beans and pork are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 2,000 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Boston Baked Beans

Oven, in the book's wordsA brisk oven

Ingredients

Directions

The book says “a brisk oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Pick over and wash the beans.

  2. Soak the beans in water for 24 hours.

Bake

  1. Place the beans in a 2-quart earthen jar and fill with water.

  2. Bake in a 400°F (200°C) oven for about 8 hours or overnight.

  3. If not using a brick oven, place the jar in a large iron pot with water and bake on the stove.

Finish and serve

  1. Two hours before serving, add molasses, salt, and salt pork to the jar.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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

What each ingredient does

Beans
Provide the main body, and their starch turns creamy during the long, slow bake.
Molasses
Adds sweetness, dark color, and a deep, caramel-like flavor to the sauce.
Salt pork
Adds fat and savory flavor that enriches the beans and sauce as they cook.

The step that matters

Adding molasses, salt, and salt pork two hours before serving. Sugar and salt added late let the beans soften fully first, since they can slow softening if added too early. Adding them near the end keeps the beans tender while still flavoring the dish throughout the final bake.

Swap the beans

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

  1. Beansthe original
  2. Peanutfits about as well
  3. Sesamefits less well
  4. Nutsfits less well

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