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 ↓
Peach Short Cake
Ingredients
Directions
Prepare
Peel and slice the peaches thinly, then sprinkle with sugar to taste.
In a bowl, combine flour, cream of tartar, baking soda, and salt.
Cream the butter and mix in the sugar.
Beat the egg yolks until foamy and add to the flour mixture.
Make and bake the shortcake
Make a well in the flour and add the butter, sugar, egg yolks, and milk.
Mix to form a batter, then fold in the beaten egg whites.
Bake immediately until done, then split and butter each half.
Serve
Fill each half liberally with the prepared peaches.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the structure of the shortcake as its proteins set during baking.
- Eggs
- Add richness and structure, and the whipped whites lighten the batter.
- Cream of tartar
- Acidifies the batter so baking soda reacts and helps the shortcake rise.
- Baking soda
- Reacts with the acid in the cream of tartar to produce gas that leavens the batter.
- Butter
- Adds fat for tenderness and flavor in the shortcake.
- Peaches
- Provide the fresh fruit filling, with sugar drawing out their juice.
The step that matters
Bake immediately until done. Baking soda and cream of tartar start reacting as soon as the batter is mixed, and the whipped egg whites trap air that expands in the oven. Delaying the bake lets gas escape and the shortcake comes out flat and dense.
