Name: Baked Brown Bread
Ingredients: 2 ½ cups sour milk; ½ cup sugar; 4 cups Graham flour; 2 teaspoons baking soda; raisins to taste; ¾ cup molasses; ¼ teaspoon salt

Why it works: Flour and raisin 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 ↓

Baked Brown Bread

Ingredients

Directions

The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.

Mix the batter

Mix sour milk and sugar in a large bowl.
Add Graham flour, baking soda, raisins, molasses, and salt. Stir until combined.
Pour the mixture into baking cans.
Let it stand for 1 hour.
Cover the cans.

Bake

Bake in a slow oven at 300°F (150°C) for 1 hour.

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

Sour milk: Its acidity reacts with baking soda to produce gas, helping the bread rise.
Graham flour: Provides the bulk and structure of the bread, with its coarse bran adding texture.
Baking soda: Reacts with the acidic sour milk to release carbon dioxide, leavening the bread.
Molasses: Adds sweetness, moisture and a dark color to the bread.

The step that matters

Bake low and slow. Baking soda and sour milk start producing gas as soon as they combine, so the batter should go into the cans and then the oven without long delays. A slow oven at 300°F bakes the thick batter through gently, setting its structure before the crust over-browns.
