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 together until light and fluffy.
Add the egg whites gradually, mixing well after each addition.
In a separate bowl, combine the flour and baking powder.
Gradually add the flour mixture to the butter mixture, mixing until just combined.
Bake
Pour the batter into a greased cake pan.
Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean.

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
- Add structure and lift to the batter as they set in the oven.
- Sugar
- Sweetens the cake and helps create a light, fluffy texture when creamed with butter.
- Flour
- Forms the main structure that holds the cake together as it bakes.
- Butter
- Adds fat for tenderness and flavor, and traps air when creamed with sugar.
- Baking powder
- Releases gas in the batter so the cake rises and becomes light.
The step that matters
Mixing the flour mixture into the butter mixture. Mixing only until just combined keeps gluten development low, so the cake stays tender rather than tough and dense.
