Why it works: Butter and walnut are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 6,832 recipes. Both carry eucalyptol, which smells eucalyptus, herbal. The science ↓
Bran Muffins
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
In a bowl, mix the bran and butter with the egg yolks.
In another bowl, combine buttermilk, baking soda, salt, and walnuts.
Add the second mixture to the first and stir well.
Gently fold in the stiffly beaten egg whites.
Bake
Pour the batter into muffin pans and bake for 30-35 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks bind and enrich the batter, while the beaten whites folded in add lift and airiness.
- Bran
- Provides the bulk and structure of the muffin, absorbing liquid as it bakes.
- Buttermilk
- Adds moisture and tang, and reacts with the baking soda to help the muffins rise.
- Baking soda
- Reacts with the acidic buttermilk to release gas, helping the muffins rise.
The step that matters
Gently fold in the stiffly beaten egg whites. Beaten egg whites trap air that gives the muffins lift. Stirring vigorously or overmixing deflates this foam, leaving dense muffins, so fold gently until just combined.
Swap the walnut
How well each one fits the dish's main ingredients (egg, butter, buttermilk):
- Pecansfits better
- Almondfits about as well
- Walnutthe original
- Peasfits less well
Fit is the average pairing score against egg, butter, buttermilk. Candidates are from the same food group and used in at least 100 recipes.
