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 ↓
Marshmallow 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 cake
Preheat the oven to 350°F (175°C).
Cream together the sugar and butter.
Add the egg whites and beat until stiff.
Stir in the sweet milk, flour, and baking powder until well combined.
Divide the batter into three layers and bake until golden.
Make the filling
For the filling, boil 2 cups of sugar and ½ cup of water until it begins to candy.
Add the marshmallows and whip until completely dissolved.
Fold in the beaten egg whites and mix until cool.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Beaten until stiff, they trap air in the batter so the cake rises light and tender.
- Butter
- Creamed with sugar, it adds fat that gives the cake a tender, rich crumb.
- Flour
- Forms the structure of the cake once the batter is baked.
- Baking powder
- Releases gas during baking, helping the layers rise.
- Marshmallows
- Melt into the boiled syrup, giving the filling its soft, sticky, airy body.
The step that matters
Boiling the sugar and water to candy stage. Sugar syrup must reach the right temperature to set the filling properly. Underheated syrup stays runny, while overheated syrup turns hard and grainy.
