Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

Ingredients
Directions
The book says “a rather hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Cream the butter and powdered sugar together.
Add the egg yolks and beat until light.
Alternate adding the milk and dry ingredients.
Fold in the well-beaten egg whites.
Bake and serve
Pour the batter into a small bread pan.
Bake in a hot oven at 400°F (200°C) until done.
Cut into squares and serve hot.

Flour and butter barely smell alike, yet cooks put them together in 124,287 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
- Eggs
- Yolks enrich and bind the batter, while whipped whites lift it for a light, airy crumb.
- Flour
- Forms the structure that holds the bread's crumb together as it bakes.
- Butter
- Adds richness and tenderness, and helps the batter cream to a light texture.
- Baking powder
- Releases gas during baking so the bread rises and becomes airy.
- Powdered sugar
- Sweetens the batter and helps the creamed butter become light and smooth.
- Sweet milk
- Adds moisture and hydrates the flour to form the batter.
The step that matters
Folding in the egg whites. Whipped whites hold air that gives the bread its lift. Stirring them in vigorously or letting the batter sit can deflate them, leaving a dense loaf.
“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.
