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
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
Preheat the oven to 350°F (175°C).
Make the batter
In a bowl, mix the flour, cream of tartar, and baking soda.
In another bowl, combine melted butter, milk, and egg.
Gradually add the wet ingredients to the dry ingredients and mix until smooth.
Divide the batter into two cake pans and bake until golden.
Assemble and serve
Once baked, split the cakes and butter them well.
Spread the mashed and sugared peaches between the layers.
Optionally, pour cream over the top before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Provides the main structure of the cakes as its proteins and starches set in the oven.
- Cream of tartar
- Acidifies the batter so it reacts with baking soda to help the cakes rise.
- Baking soda
- Reacts with the acid in the batter to release gas, lifting the cakes as they bake.
- Egg
- Adds structure and richness, helping bind the batter as it sets.
- Milk
- Adds moisture and hydrates the flour so the batter forms a smooth, pourable mixture.
- Melted butter
- Adds fat for tenderness and flavor in the cake crumb.
The step that matters
Gradually add the wet ingredients to the dry ingredients and mix until smooth. Adding the liquid slowly and mixing just until smooth keeps lumps out while avoiding overmixing, which develops gluten and can make the cakes tough. Combining the acid and baking soda evenly ensures a consistent rise.
