Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Chocolate Ice Cream 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
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Add the egg yolks and mix well.
Sift the flour and baking powder together, then add to the mixture alternately with the cold water.
Pour the boiling water over the grated chocolate and mix until smooth.
Combine the chocolate mixture with the batter and flavor to taste.
Pour the batter into layers or a loaf pan and bake until a toothpick comes out clean.
Make the icing
For the icing, boil water and granulated sugar until clear.
Beat the egg whites to stiff peaks, then slowly pour the boiling syrup over them while beating continuously.
Continue beating until the icing is stiff enough for the cake.

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 whip into the icing for structure.
- Butter
- Creamed with sugar, it traps air and adds tenderness and richness to the cake.
- Sugar
- Sweetens the cake and, boiled into syrup, gives the icing its stiff, glossy body.
- Flour
- Provides the structure that sets the cake as it bakes.
- Baking powder
- Releases gas in the batter so the cake rises and becomes light.
- Grated chocolate
- Adds chocolate flavor and color to the batter.
The step that matters
Pouring the boiling syrup into the egg whites. The syrup must be added slowly while beating constantly. Pouring it too fast or stopping the beating can cook the whites unevenly or deflate them, so the icing will not hold its stiff peaks.
