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 ↓
Potato Caramel 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.
Make the batter
Cream the butter and sugar together until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Alternate adding the flour and mashed potato to the mixture.
Stir in the remaining ingredients until well combined.
Bake
Pour the batter into a greased loaf pan.
Bake at 350°F (175°C) 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 sugar to trap air and add richness and tender texture.
- Eggs
- Bind the batter and add structure as the cake sets in the oven.
- Flour
- Forms the main structure of the cake as it bakes.
- Mashed potato
- Adds moisture and a soft, dense crumb to the cake.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
- Granulated sugar
- Sweetens the cake and helps create a tender, browned crust.
The step that matters
Creaming the butter and sugar. Beating until light and fluffy works air into the fat, which helps the cake rise and gives it a fine, tender texture. Under-creamed butter leaves a dense, heavy crumb.
