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 ↓
Bran Bread
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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
In a large bowl, mix the bran flour, baking soda, all-purpose flour, and salt.
In another bowl, combine the milk, molasses, and chopped raisins.
Mix and bake
Pour the wet ingredients into the dry ingredients and stir until just combined.
Pour the batter into a loaf pan or gem pans.
Bake for 30-40 minutes or until a toothpick inserted in the center comes out clean.

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
- Bran flour
- Adds fibre and a dense, hearty structure to the crumb.
- Baking soda
- Reacts with the molasses acidity to lift the batter and help it rise.
- All-purpose flour
- Provides gluten structure so the loaf holds its shape.
- Molasses
- Adds sweetness, dark colour and moisture, and its acidity activates the baking soda.
- Milk
- Hydrates the flours and helps the batter set into a moist crumb.
The step that matters
Stir the wet and dry ingredients until just combined. Overmixing develops gluten in the all-purpose flour, which makes the bread tough and dense. Stopping once no dry streaks remain keeps the crumb tender and lets the baking soda lift the batter evenly.
