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 ↓
Mountain 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.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
In a large bowl, cream together the butter and sugar.
Add the egg whites and flour alternately, mixing well after each addition.
Stir in the milk until smooth.
In a separate bowl, mix the cream of tartar and baking soda with the flour.
Combine the flour mixture with the batter and mix well.
Bake
Pour the batter into shallow tin pans and bake until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar to trap air and add richness and tender texture.
- Egg whites
- Add structure and lift to the batter as they set in the oven.
- Flour
- Forms the main structure of the cake as its proteins set during baking.
- Cream of tartar
- Stabilises the egg whites and works with baking soda to help the cake rise.
- Baking soda
- Reacts with the acidic cream of tartar to produce gas that leavens the cake.
- White sugar
- Sweetens the cake and helps create a tender crumb when creamed with butter.
The step that matters
Adding the egg whites and flour alternately. Adding the flour in portions alongside the egg whites and mixing well after each addition keeps the batter smooth and emulsified, so the cake bakes evenly without curdling or becoming dense.
“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.
