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 ↓
Plain Cup 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).
Beat the butter until light, then gradually add the sugar while continuing to beat until creamy.
Add the beaten eggs and milk, mixing well.
Stir in the flour, baking soda, and cream of tartar.
Flavor with lemon or nutmeg as desired.
Bake
Pour the batter into loaf or sheet pans.
Bake for 40 minutes if in loaves, or 20 minutes if in sheets, until the top looks well done.

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 a tender, rich crumb.
- Eggs
- Add structure and richness, helping the batter hold together as it bakes.
- Flour
- Forms the main structure of the cake as its proteins set in the oven.
- Baking soda
- Reacts with the acid in the batter to produce gas that lifts the cake.
- Cream of tartar
- Acidic component that works with the baking soda to help the cake rise and stay tender.
The step that matters
Beating the butter and sugar until creamy. Creaming works air into the fat, and that trapped air helps lift the cake. Beating too little leaves a dense cake, while the leavening reaction depends on the acid and soda being evenly mixed through the batter.
