Name: Graham Bread
Ingredients: 4 cups graham flour; ½ cup brown sugar; ½ cup molasses; 1 teaspoon salt; 1 teaspoon baking soda; 1 pint sour milk or buttermilk

Why it works: Sugar and molasses are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 9,225 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓

Oven, in the book's wordsA slow oven

Ingredients

Directions

The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

Preheat the oven to 300°F (150°C).

Make the batter

In a large bowl, mix graham flour, brown sugar, molasses, salt, and baking soda.
Stir in the sour milk or buttermilk until well combined.
Pour the batter into a greased 2-quart loaf pan.

Bake

Bake for 2 hours or until a toothpick inserted in the center comes out clean.

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

What each ingredient does

Graham flour: Forms the bulk of the loaf and gives it a coarse, hearty structure.
Sour milk or buttermilk: Provides moisture and acidity that react with the baking soda to lift the loaf.
Baking soda: Reacts with the acidic sour milk or buttermilk to produce gas that makes the bread rise.
Molasses: Adds moisture, deep flavour and dark colour, and helps keep the loaf tender.
Brown sugar: Adds sweetness and moisture, and contributes to browning and a soft crumb.

The step that matters

Bake for the full time at low heat. Baking soda starts producing gas as soon as it meets the acidic liquid, so the batter should go into the oven promptly. The low 300°F heat cooks the dense, sugary batter through gently, and a toothpick test confirms the center is set before the loaf is removed.
