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 ↓
Bran Muffins
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 bowl, mix the bran and flour together.
In another bowl, combine the sour milk, molasses, and baking soda.
Mix and bake
Pour the wet ingredients into the dry ingredients and stir until just combined.
Spoon the batter into a greased muffin tin.
Bake for 20-25 minutes or until a toothpick comes out clean.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Adds fiber-rich bulk and a hearty, slightly nutty texture to the muffin crumb.
- Flour
- Provides the structure that holds the muffins together as they bake.
- Sour milk
- Supplies moisture and acidity that reacts with the baking soda to help the muffins rise.
- Molasses
- Adds sweetness, moisture, and a deep flavor that also helps browning.
- Baking soda
- Reacts with the acidic sour milk to produce gas, lifting the batter as it bakes.
The step that matters
Stir the batter until just combined. Overmixing develops gluten in the flour, which makes muffins tough and tunnelled. Stopping once the dry ingredients are moistened keeps the texture tender, and the baking soda's rising reaction starts as soon as the wet and dry ingredients meet.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
