Why it works: Nuts and flour are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 1,180 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Plain Bran Muffins
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 400°F (200°C).
Make the batter
In a bowl, cream together the shortening, sugar, and egg.
In another bowl, sift together the flour, salt, and baking powder.
Add the dry ingredients alternately with the sweet milk to the creamed mixture.
Finally, add the bran and beat for one minute.
Bake
Spoon the batter into greased and flour-dusted muffin tins.
Bake for about 20 minutes or until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the muffin together as it bakes.
- Egg
- Binds the batter and adds structure and richness to the crumb.
- Baking powder
- Releases gas in the batter, helping the muffins rise and turn light.
- Shortening
- Adds fat that tenderises the crumb and carries flavour.
- Bran
- Adds fibre and bulk, giving the muffins a coarser, denser texture.
- Sweet milk
- Adds moisture that hydrates the flour and gives the batter its loose consistency.
The step that matters
Add the bran last and beat only for one minute. Overmixing once flour is in develops gluten, which toughens the muffins. Bran absorbs liquid, so a brief final mix keeps the batter moist and the texture tender.
Swap the nuts
The recipe marks nuts as optional. How well each one fits the dish's main ingredients (sugar, egg, milk, flour):
- Almondfits better
- Milletfits better
- Chestnutfits better
- Nutsthe original
Fit is the average pairing score against sugar, egg, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
