Why it works: Milk and butter 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 ↓
Martha Washington 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).
In a bowl, mix sugar, sweet milk, flour, egg, baking powder, and butter until smooth.
Divide the batter into three layers and bake until golden.
Make the custard
For the custard, scald the milk in a saucepan.
In a separate bowl, beat together the sugar, flour, egg, and corn starch.
Add the beaten mixture to the scalded milk and boil until thick.
Flavor the custard as desired and let it cool.
Assemble
Spread the cooled custard between the layers of cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and enrich the custard, helping it set and giving structure to the cake.
- Flour
- Provides the structure of the cake and thickens the custard as it cooks.
- Butter
- Adds fat for tenderness and a richer crumb in the cake.
- Sugar
- Sweetens the cake and custard and contributes to browning of the layers.
- Baking powder
- Releases gas in the batter so the layers rise and become light.
- Corn starch
- Thickens the custard so it holds its shape between the layers.
The step that matters
Boil the custard until thick. Starch in the flour and corn starch only thickens fully when it reaches a boil and is stirred. Undercooked custard stays thin and runny and will not hold between the cake layers.
“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.
