Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Delicate Cake
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°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
Preheat the oven to 400°F (200°C).
Cream the butter and sugar together until light and fluffy.
Add the flour gradually, mixing well.
Make the batter
Beat the egg whites until stiff peaks form.
Dissolve the baking soda in the sweet cream and add the cream of tartar.
Fold the egg whites and cream mixture into the batter.
Add flavoring to taste and mix gently.
Bake
Pour the batter into a prepared cake pan and bake for about 25‑30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar to trap air and give a tender, rich crumb.
- Egg whites
- Whipped to stiff peaks, they lift the cake and give it a light, airy structure.
- Flour
- Provides the main structure that holds the cake once it sets in the oven.
- Baking soda
- Reacts with the acidic cream of tartar and cream to release gas, helping the cake rise.
- Cream of tartar
- Acidifies the mixture, stabilizing the whipped egg whites and reacting with the baking soda.
- Sugar
- Sweetens the cake and helps create a tender crumb when creamed with butter.
The step that matters
Folding the egg whites into the batter. Whipped egg whites hold air that gives the cake its lift. Stirring vigorously or overmixing deflates the foam, leaving a dense, flat cake, so fold gently with a spatula until just combined.
