Why it works: Milk and butter 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 ↓
Park Street 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.
Make the batter
Preheat your oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Add the beaten yolks of the eggs and mix well.
Stir in the milk, then gradually add the flour.
Fold in the beaten egg whites.
Dissolve the baking soda and cream of tartar in a little milk, then add to the batter.
Bake and ice
Pour the batter into a greased cake pan and bake until golden.
For the icing, boil the white granulated sugar until ready.
Remove from heat and stir in the chocolate until smooth.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks enrich the batter and whites, folded in, add lightness and structure as the cake sets.
- Flour
- Provides the main structure that sets as the cake bakes.
- Butter
- Creamed with sugar to trap air and add tenderness and richness.
- Sugar
- Sweetens the cake and, creamed with butter, helps give a light, fluffy texture.
- Baking soda
- Reacts with the cream of tartar to produce gas that helps the cake rise.
- Cream of tartar
- Acidifies the batter so it reacts with baking soda, helping the cake rise.
The step that matters
Dissolve the baking soda and cream of tartar in a little milk. Baking soda and cream of tartar must be fully dissolved and evenly distributed through the batter, or the leavening reacts unevenly, producing patchy rise and uneven texture in the finished cake.
