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 ↓
Hickory Nut 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 layers
Preheat the oven to 350°F (175°C).
Beat together 4 eggs, 2 cups sugar, ½ cup butter, 2½ cups flour, and 2 teaspoons baking powder.
Divide the batter into layers and bake until golden.
Make the cream
Beat together 2 eggs, 1 cup sugar, 2 heaping tablespoons cornstarch, and 1 cup chopped hickory nuts for the cream.
Stir the mixture into 1 pint of boiling milk and cook until thick like custard.
Assemble
Let the cream cool, then spread it between the baked layers.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide structure to the batter and thicken the cream as they set when heated.
- Butter
- Adds fat for tenderness and a rich flavour in the cake.
- Flour
- Forms the structure of the cake layers as the batter sets in the oven.
- Baking powder
- Releases gas in the batter, helping the layers rise and turn light.
- Cornstarch
- Thickens the cream into a smooth custard as it cooks in boiling milk.
- Hickory nut meats
- Add a nutty flavour and texture to the cream filling.
The step that matters
Cooking the cream. Stirring the egg and cornstarch mixture into boiling milk and cooking it until thick sets the custard. Cornstarch needs to reach a boil to reach full thickening, and eggs can curdle if overheated, so keep stirring.
