Why it works: Flour and almond are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 8,673 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
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 together the butter and sugar.
Gradually add the corn starch and flour while stirring.
Mix the baking powder with the flour before adding.
Divide the batter into layers.
Bake the layers until golden.
Make the icing
Beat the 4 egg whites until light.
Boil the 4 cups of sugar with ½ pint of water until clear and thick.
Slowly pour the hot syrup over the beaten egg whites.
Stir the mixture well.
Dissolve the citric acid in a small amount of water.
Add the dissolved citric acid to the icing.
Assemble
Spread the icing between the layers and on top after it has cooled.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with the sugar to give the cake tenderness and a rich flavour.
- Egg whites
- Beaten to a foam, they give the icing its light, airy structure.
- Baking powder
- Releases gas in the batter, helping the layers rise and turn light.
- Corn starch
- Softens the flour's gluten, giving the layers a finer, more tender crumb.
- Sugar
- Sweetens the cake and, boiled into syrup, sets the icing.
- Citric acid
- Adds acidity that helps stabilise the icing and keeps it from turning grainy.
The step that matters
Pouring the hot syrup into the egg whites. The syrup must be hot and poured slowly in a thin stream while beating, so it cooks the egg whites into a stable, glossy foam instead of deflating them or scrambling.
