Why it works: Flour and almond are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 8,673 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Feather Cake
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.
Prepare
Preheat the oven to 400°F (200°C).
Make the batter
Beat the egg whites until stiff.
In a large bowl, cream together the butter and sugar.
Gradually add the flour, sweet milk, and baking powder, mixing well.
Add the bitter almond flavoring and mix until combined.
Pour the batter into a greased cake pan.
Bake
Bake for 35 to 40 minutes or until a toothpick comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped to stiff foam, they trap air and give the cake its light, feathery structure.
- Butter
- Creamed with sugar, it traps air and adds richness and tenderness to the crumb.
- Sugar
- Creams with butter for texture and sweetens the cake while helping it brown.
- Flour
- Forms the cake's main structure as its proteins set during baking.
- Baking powder
- Releases gas in the batter so the cake rises and becomes airy.
The step that matters
Folding in the stiff egg whites. Whipped whites hold the cake's air. Mixing them in too vigorously knocks out bubbles, while under-mixing leaves streaks, so the cake rises less evenly and turns 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.
