Name: Pumpkin Loaf
Ingredients: 2 cups buttermilk; 3 cups wheat flour; 3 cups corn meal; 1 cup stewed pumpkin; 1 cup molasses; ½ cup butter; 2 eggs; 1 tablespoon baking soda

Why it works: Wheat and corn match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 465 recipes. Both carry hexanal, which smells green, grassy. The science ↓

Pumpkin Loaf

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Make the batter

Combine buttermilk, wheat flour, cornmeal, stewed pumpkin, molasses, butter, eggs, and baking soda in a large bowl.
Mix until well combined.
Pour the mixture into a greased loaf pan.

Steam and bake

Steam for 1.5 hours.
Bake in a preheated oven at 350°F (175°C) for 30 minutes.

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

Eggs: Bind the batter and add structure as they set during cooking.
Baking soda: Reacts with the acidic buttermilk and molasses to produce gas that lifts the loaf.
Buttermilk: Adds moisture and acidity that activates the baking soda.
Wheat flour: Provides gluten and starch that form the loaf's main structure.
Cornmeal (in the method): Adds coarse texture and body to the crumb.
Molasses: Adds sweetness, dark color, and moisture.
