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 ↓

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 large bowl, cream together the butter and sugar until light and fluffy.
Add the sweet milk and mix well.
In another bowl, combine the flour, cream of tartar, and baking soda.
Gradually add the dry ingredients to the wet mixture, mixing until just combined.
In a separate bowl, beat the egg whites until stiff peaks form, then gently fold them into the batter.
Bake
Pour the batter into a prepared cake pan, ensuring the white part is around the edge.
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
- Butter
- Creams with the sugar to add tenderness and a fine, rich crumb.
- White sugar
- Sweetens the cake and helps hold air when creamed with the butter.
- Flour
- Forms the cake's structure once the batter sets in the oven.
- Egg whites
- Beaten to stiff peaks and folded in, they lighten the batter and give it lift.
- Cream of tartar
- Stabilizes the beaten egg whites and works with baking soda to aid rising.
- Baking soda
- Reacts with the acidity in the batter to produce gas that helps the cake rise.
The step that matters
Folding in the beaten egg whites. Stiff whites hold the air that lifts the cake. Folding gently keeps that air in; vigorous stirring deflates the foam and leaves a dense, flat cake.
