Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓

Ingredients
Directions
The book says “a quick oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure. The book gives no cooking times; 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).
Cream the butter and sugar together until light and fluffy.
Add the milk and eggs (reserve the whites of 3 eggs for icing) and mix well.
In a separate bowl, combine the flour, baking powder, baking soda, and cream of tartar.
Gradually add the dry ingredients to the wet mixture, mixing until just combined.
Bake and ice
Divide the batter into three deep jelly tins and bake for 25-30 minutes or until a toothpick comes out clean.
For the icing, beat the reserved egg whites until stiff peaks form.
Gradually add the powdered sugar, grated chocolate, and vanilla, mixing until smooth.
Once the cakes are cool, spread icing between the layers and on top.

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, giving the cake a light, tender crumb and rich flavor.
- Eggs
- Add structure and richness, and their whites whip into stiff peaks for the icing.
- Flour
- Forms the cake's main structure once its proteins set in the oven.
- Baking soda
- Reacts with acidic components to produce gas that helps the cake rise.
- Baking powder
- Releases gas during baking to give the cake lift and an even rise.
- Sugar
- Sweetens the cake and helps create a soft, tender texture when creamed.
The step that matters
Mixing the dry ingredients into the wet mixture. Overmixing once flour is added develops gluten, which can make the cake tough. Mixing only until just combined keeps the crumb tender.
