Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
White Pound Cake
Ingredients
Directions
The book says “a cool oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Make the cake
Preheat the oven to 300°F (150°C).
Cream the butter and sugar together until light and fluffy.
Add the egg whites and mix well.
Sift the flour with the baking powder.
Gradually fold the sifted flour into the mixture.
Pour the batter into a prepared cake pan.
Place the pan in the oven, gradually increasing the heat.
Make the icing
For the icing, boil 3 cups of sugar with 1 cup of water until clear.
Beat 3 egg whites to stiff peaks.
Slowly pour the boiling sugar mixture over them while beating continuously for 10 minutes.
Finish
Frost the cake while both the cake and icing are still warm.

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
- Butter
- Creamed with sugar to trap air, giving the cake a tender, rich crumb.
- Egg whites
- Provide structure as they set in the batter, and form stiff foam in the icing.
- Flour
- Forms the cake's main structure once its proteins set during baking.
- Sugar
- Sweetens the cake and helps create a light, fluffy creamed texture.
- Baking powder
- Releases gas in the batter so the cake rises and becomes lighter.
The step that matters
Pouring the boiling sugar syrup into the egg whites. The syrup must be boiling hot and poured slowly while beating constantly. This cooks the egg whites into a stable, glossy meringue; pouring too fast or letting the mixture cool can leave the icing runny or grainy.
