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 ↓
Milk Chocolate Cake
Ingredients
Directions
The book gives no oven temperature. The 375°F (190°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the batter
Cream the butter and gradually add the sugar.
Add 1 unbeaten egg and beat thoroughly.
Add the second egg and continue beating.
Alternately add the sifted flour and salt with the sour milk mixed with vanilla.
Melt the chocolate over hot water and beat it in thoroughly.
Dissolve the baking soda in the vinegar and add it last.
Bake
Pour the batter into two greased 9-inch pans.
Bake at 375°F (190°C) for 25-30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with the sugar to trap air and give the cake a tender, rich crumb.
- Eggs
- Add structure and richness, binding the batter as it sets in the oven.
- Cake flour
- Provides the structure that holds the cake's rise and crumb once baked.
- Sour milk or buttermilk
- Adds moisture and acidity that tenderises the crumb and activates the baking soda.
- Bitter chocolate
- Supplies the chocolate flavour and colour that define the cake.
- Baking soda
- Reacts with the acid in the vinegar and sour milk to produce gas that lifts the batter.
The step that matters
Adding the baking soda in vinegar last. The soda and vinegar react immediately to release gas, so the batter should go into the pans and into the oven right away to keep the rise.
