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 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 your oven to 350°F (175°C).
In a large bowl, cream the butter and sugar until light and fluffy.
Gradually add the flour and mix until well combined.
In a separate bowl, beat the egg whites to stiff peaks.
Gently fold the egg whites into the batter along with the mace and citron.
Bake and cool
Pour the batter into a greased cake pan and bake for about 25-30 minutes or until a toothpick comes out clean.
Let the cake cool before frosting.

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 peaks, they trap air that gives the cake its light, airy rise.
- Butter
- Creamed with sugar to trap air and add richness and a tender crumb.
- All-purpose flour
- Provides the structure that holds the cake together as it sets in the oven.
- White sugar
- Sweetens the cake and, creamed with butter, helps build a light, fluffy texture.
The step that matters
Folding in the egg whites. Stiff egg whites hold a lot of trapped air, and vigorous stirring deflates them, leading to a dense cake. Fold gently, cutting through the batter, so the cake rises well.
Swap the mace
How well each one fits the dish's main ingredients (sugar, flour, butter, egg):
- Cinnamonfits better
- Nutmegfits better
- Jalapenofits better
- Macethe original
Fit is the average pairing score against sugar, flour, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
“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.
