Name: Whole Wheat Brown Bread
Ingredients: 2 cups fine whole wheat flour; 1 cup coarse whole wheat flour; 1 cup white flour; ¾ cup molasses; 2 cups sour milk; ½ teaspoon salt; 1 teaspoon baking soda dissolved in a little water

Why it works: Wheat and milk are a kitchen classic. They rank in the top 6% of all ingredient pairs, and cooks put them together in 2,418 recipes. Both carry (e,z)-2,6-nonadienal, which smells cucumber, melon. The science ↓

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 the batter

Mix the flours together in a large bowl.
Add the molasses, sour milk, salt, and dissolved baking soda.
Stir until the mixture is well combined.

Bake

Pour the batter into a greased loaf pan.
Bake in a slow oven at 300°F (150°C) for one 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

Whole wheat flour: Provides the main structure and the hearty, nutty body of the loaf.
White flour: Adds gluten that gives the loaf a lighter, more cohesive crumb.
Molasses: Adds sweetness, moisture, and a dark color through browning.
Sour milk: Its acidity reacts with the baking soda so the bread rises.
Baking soda: Reacts with the acid in the sour milk to produce gas that leavens the loaf.

The step that matters

Stirring the batter until well combined. Baking soda must be evenly distributed through the batter so it reacts with the sour milk and rises uniformly. Uneven mixing leaves dense pockets or bitter spots in the loaf.
