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 ↓
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.
Prepare the batter
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
In a separate bowl, combine the flour, baking soda, and cream of tartar.
Gradually add the dry ingredients to the butter mixture, alternating with the milk.
Melt the chocolate and stir it into the batter along with lemon flavoring.
Bake
Pour the batter into prepared cake pans 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
- Butter
- Creamed with sugar to trap air, giving the cake a tender, rich crumb.
- Eggs
- Add structure and richness, binding the batter as it sets in the oven.
- Flour
- Forms the main structure of the cake as its proteins set during baking.
- Baking soda
- Reacts with the acid in the batter to produce gas that helps the cake rise.
- Cream of tartar
- Acidifies the batter, working with baking soda to help the cake rise and stay tender.
- Sugar
- Sweetens the cake and, creamed with butter, helps create a light texture.
The step that matters
Alternating dry ingredients with milk. Adding the flour mixture gradually and alternating it with milk keeps the batter smooth and prevents overmixing. Overmixing develops gluten, which can make the cake tough.
