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.
Make the marshmallow mixture
Boil sugar and 1 cup of water until it ropes well from a spoon.
Break marshmallows into small pieces.
Add the pieces to the boiling syrup and stir until they melt.
Pour the melted mixture into the well-beaten egg whites and beat until smooth and cold.
Make and bake the cake
Cream together the butter and sugar.
Add the egg whites, milk, water, flour, and baking powder.
Pour the batter into prepared cake pans.
Bake at 350°F (175°C) until a toothpick comes out clean.
Make the filling and finish
Cook 2 cups of white sugar and ½ cup of cold water until it begins to drop thick from the spoon.
Mash the fresh marshmallows until dissolved.
Pour the mixture into 3 beaten egg whites and mix well.
Spread the filling on the cooled cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Beaten whites trap air, giving the cake and marshmallow mixture a light, airy structure.
- Flour
- Provides the main structure that holds the cake's crumb together as it bakes.
- Butter
- Adds fat for tenderness and richness in the creamed batter.
- Sugar
- Sweetens the cake and, when cooked into syrup, sets the marshmallow-style filling.
- Baking powder
- Releases gas during baking, helping the cake rise.
- Marshmallows
- Melt into the syrup to give the mixture a soft, marshmallow-like texture and sweetness.
The step that matters
Pour the hot marshmallow mixture into the beaten egg whites while beating. Hot syrup poured slowly into beaten whites, with continuous beating, cooks the whites gently and keeps the foam smooth. Pouring too fast or letting the foam deflate causes lumps and a dense, weepy texture.
“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.
