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 says “a slow oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat your oven to 350°F (175°C).
Make the batter
In a bowl, cream together the sugar and butter until light and fluffy.
Add the milk and mix well.
In another bowl, combine the flour, baking soda, cream of tartar, and nutmeg.
Gradually add the dry ingredients to the wet mixture, stirring until just combined.
Beat in the eggs until fully incorporated.
Bake
Pour the batter into a greased cake pan and bake for 25-30 minutes or 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
- Butter
- Creaming with sugar traps air, giving the cake a light, tender crumb and rich flavour.
- Eggs
- Add structure and moisture, binding the batter as they set in the oven.
- Flour
- Forms the main structure of the cake once its starches set with heat.
- Baking soda
- Reacts with the acid in cream of tartar to produce gas that makes the cake rise.
- Cream of tartar
- Provides acidity that activates the baking soda, helping the cake rise and stay tender.
- Sugar
- Sweetens the cake and, creamed with butter, helps give it a light texture.
The step that matters
Stirring the dry ingredients into the wet mixture. Overmixing once the flour is added develops gluten, which can make the cake tough. Stir only until just combined so the batter stays tender and the leavening works evenly.
Swap the nutmeg
How well each one fits the dish's main ingredients (sugar, butter, milk, flour, cream, egg):
- Nutmegthe original
- Cinnamonfits about as well
- Capersfits less well
- Jalapenofits less well
Fit is the average pairing score against sugar, butter, milk, flour, cream, egg. Candidates are from the same food group and used in at least 100 recipes.
