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 ↓
Chocolate 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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the batter
Preheat the oven to 350°F (175°C).
In a bowl, cream together the butter and sugar until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Stir in the sour milk, baking soda, and vanilla extract.
Melt the Baker's chocolate and mix it into the batter.
Gradually add the flour, mixing until just combined.
Bake and ice
Pour the batter into a greased cake pan and bake for 30-35 minutes.
For the icing, mix sweet milk with powdered sugar until it reaches a spreadable consistency.
Once the cake is cool, spread the icing on top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Add structure and richness, binding the batter as it sets in the oven.
- Butter
- Adds fat and tenderness, and creaming it with sugar traps air for a lighter crumb.
- Sugar
- Sweetens the cake and helps create a tender crumb when creamed with butter.
- Sour milk
- Its acidity reacts with the baking soda to help the cake rise and keeps it moist.
- Baking soda
- Reacts with the acidic sour milk to produce gas that makes the cake rise.
- All-purpose flour
- Provides the main structure that sets as the cake bakes.
The step that matters
Mixing the flour in gradually and only until combined. Once flour meets liquid, gluten begins to form; overmixing makes the cake tough and dense. Stopping as soon as the flour is incorporated keeps the crumb tender.
