Name: Steamed Brown Bread
Ingredients: 4 cups cornmeal; 2 cups all-purpose flour; 1 cup molasses; 2 cups sour milk; 2.5 to 3 cups sweet milk or water; 1 teaspoon baking soda; 1.5 teaspoons salt

Why it works: Flour and milk are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Flour and milk barely smell alike, yet cooks put them together in 78,219 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Cornmeal: Forms the bulk of the crumb and gives the bread its characteristic texture and corn flavor.
All-purpose flour: Adds gluten-based structure so the steamed loaf holds together.
Molasses: Adds sweetness, dark color, and moisture with a deep, robust flavor.
Sour milk: Its acidity reacts with the baking soda to lift and lighten the batter.
Baking soda: Reacts with the acidic sour milk and molasses to produce gas that leavens the bread.

The step that matters

Steam for 3.5 to 4 hours. Steaming must run long and steadily so the heat fully sets the batter through the center. Too little time leaves the loaf dense and gummy, and the mold needs enough water to keep steam going the whole time.
