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 moderately quick oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
Cream together the sugar and butter.
Add the flour, milk, and well-beaten egg to the mixture.
Stir in the cream of tartar and baking soda.
Flavor the batter delicately with vanilla.
Bake
Divide the batter into two round cake pans, filling them about an inch deep.
Bake in the preheated oven until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and add structure as the cake sets.
- Flour
- Forms the main structure of the cake crumb.
- Butter
- Adds richness and tenderness to the crumb.
- Sugar
- Sweetens the cake and helps it brown as it bakes.
- Baking soda
- Reacts with the acid in the batter to help the cake rise.
- Cream of tartar
- Acidifies the batter and works with baking soda to help it rise.
The step that matters
Stir in the cream of tartar and baking soda. Baking soda needs an acid to react and create lift, and the reaction is strongest soon after mixing. Adding the leavening late and then baking promptly helps the cake rise well, while overmixing can toughen the crumb.
