Why it works: Raisin and flour match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,075 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Boston Brown Bread

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.

Make the batter

  1. In a bowl, combine the beaten egg, molasses, sour milk, and other ingredients.

  2. Pour the mixture into well-greased brown bread cans.

Bake

  1. Cover each can and place them in a shallow pan with 1½ inches of water.

  2. Bake in a moderate oven at 350°F (175°C) for about 1½ hours.

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

What each ingredient does

Eggs
Binds the batter and adds structure as it sets.
Molasses
Adds sweetness, dark colour and moisture to the bread.
Sour milk
Its acidity reacts with the baking soda to help the bread rise.
Baking soda
Reacts with the acidic sour milk to produce gas that leavens the bread.
Whole wheat or graham flour
Provides the bulk of the structure and a hearty, nutty texture.
Yellow cornmeal
Adds coarser texture and body to the crumb.

The step that matters

Cover each can and bake in a water bath. The covered cans and surrounding water create a moist, steamy heat that keeps the bread from drying out and lets it rise evenly before the crust sets.
