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 cake batter
Preheat your oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Add the beaten egg yolks 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 make the icing
Pour the batter into a greased cake pan and bake until a toothpick comes out clean.
For the icing, boil the white granulated sugar with water until it reaches the soft ball stage.
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 lift and a light crumb.
- Baking soda
- Reacts with the acidic cream of tartar to release gas, helping the cake rise.
- Cream of tartar
- Provides acidity that activates the baking soda and helps stabilise the batter's structure.
- Butter
- Creamed with sugar to trap air and add richness and tenderness to the crumb.
- All-purpose flour
- Forms the cake's structure as its proteins set during baking.
- Sugar
- Creamed with butter to aid aeration and add sweetness and browning.
The step that matters
Folding in the beaten egg whites. Egg whites hold the air that lifts the cake. Stirring them vigorously knocks out air, while gentle folding keeps the batter light and prevents a dense, flat result.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
