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 Cake. No. 2
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
Cream the butter and sugar together.
Add the milk and mix well.
In a separate bowl, combine the flour, baking powder, cinnamon, cloves, and grated nutmeg.
Gradually add the dry ingredients to the butter mixture.
Fold in the grated boiled potatoes and chopped pecans.
Gently fold in the beaten egg whites.
Bake
Pour the batter into a greased cake pan and bake until a toothpick comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Beaten whites trap air, giving the cake lift and a light crumb.
- Butter
- Creamed with sugar, it adds fat that gives a tender, rich texture.
- Flour
- Forms the structure that holds the cake together as it bakes.
- Baking powder
- Releases gas in the oven, helping the cake rise.
- Boiled potatoes
- Grated potato adds moisture that keeps the crumb soft.
- Sugar
- Sweetens the cake and helps brown it while creaming in air pockets.
The step that matters
Fold in the beaten egg whites. Folding gently keeps the air trapped in the whites. Stirring hard knocks that air out, so the cake rises less and turns dense.
Swap the pecans
How well each one fits the dish's main ingredients (butter, sugar, milk, flour, potato, egg, nutmeg):
- Almondfits better
- Chestnutfits better
- Milletfits better
- Pecansthe original
Fit is the average pairing score against butter, sugar, milk, flour, potato, egg, nutmeg. Candidates are from the same food group and used in at least 100 recipes.
