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 ↓
Puff Cake
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the batter
Preheat the oven to 350°F (175°C).
In a bowl, cream together the sugar and butter.
Add the milk and mix well.
Gradually add the flour and baking powder, stirring until combined.
Fold in the beaten egg whites gently.
Add the almond extract or nutmeg, and mix in the currants or citron.
Bake
Pour the batter into a greased cake pan and bake for 25-30 minutes or until golden.

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
- Egg whites
- Whipped to stiff foam, they trap air that lifts the cake as it bakes.
- Baking powder
- Releases gas in the batter, helping the cake rise and turn light.
- Butter
- Creamed with sugar, it adds richness and a tender crumb.
- Flour
- Provides the structure that holds the cake together as it sets.
- Sugar
- Adds sweetness and helps browning and a soft crumb when creamed with butter.
The step that matters
Folding in the beaten egg whites. Stirring vigorously or overmixing knocks out the air whipped into the egg whites, so the cake rises less and bakes up dense instead of light.
Swap the currant
How well each one fits the dish's main ingredients (sugar, flour, milk, butter, egg, almond):
- Vanillafits better
- Raisinfits better
- Figfits better
- Currantthe original
Fit is the average pairing score against sugar, flour, milk, butter, egg, almond. Candidates are from the same food group and used in at least 100 recipes.
