Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Delicate 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 mixing bowl, cream the butter and sugar together until light and fluffy.
Add the beaten egg whites and sweet milk, mixing well.
In a separate bowl, combine the flour, cream of tartar, and baking soda.
Gradually add the dry ingredients to the wet mixture, stirring 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.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Beaten whites trap air, giving the cake lift and a light, airy structure.
- Butter
- Creaming with sugar traps air and adds fat for a tender crumb.
- All-purpose flour
- Its proteins set during baking to form the cake's structure.
- Cream of tartar
- Acidifies the batter, stabilizing the whites and helping the cake rise.
- Baking soda
- Reacts with the acid in the batter to produce gas, helping the cake rise.
The step that matters
Gradually add the dry ingredients to the wet mixture, stirring until just combined.. Overmixing once flour is added develops gluten, which can make the cake tough and dense. Stir only until no dry flour streaks remain.
