Why it works: Milk and flour 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 ↓
Feather Muffins
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Beat together the lard and sugar.
Add the egg yolk, milk, flour, baking powder, and salt.
Fold in the well-beaten egg white.
Bake
Pour the mixture into a greased muffin tin.
Bake in a hot oven at 400°F (200°C) until golden.

Milk and flour 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
- Flour
- Provides the structure that holds the muffins together as they bake.
- Egg white
- Whipped air and structure help the muffins rise light and feathery.
- Egg yolk
- Adds richness and helps bind the batter and set the crumb.
- Baking powder
- Releases gas during baking, lifting the batter so the muffins rise.
- Lard
- Adds fat that tenderises the crumb and gives a soft texture.
- Milk
- Supplies moisture that hydrates the flour and helps form the batter.
The step that matters
Fold in the well-beaten egg white. Folding gently keeps the air trapped in the beaten egg white. Stirring hard would knock that air out, and the muffins would rise less and turn out denser.
“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.
