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 ↓
Economical Cake
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Beat the butter until creamy.
Whisk the egg whites until stiff peaks form.
Make the batter
In a large bowl, combine flour, sugar, butter, currants, and milk.
Mix well, then gently fold in the beaten egg whites.
Stir in the baking soda just before baking.
Pour the mixture into a buttered mold.
Bake
Bake for 1.5 hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Provides the structure that holds the cake together as it bakes.
- Egg whites
- Whipped to stiff peaks, they trap air and lighten the crumb.
- Baking soda
- Reacts with the acidity in the batter to release gas and help it rise.
- Butter
- Adds fat for tenderness and richness in the crumb.
- Sugar
- Sweetens the cake and contributes to its tender texture and browning.
- Currants
- Supply fruit pieces and sweetness throughout the cake.
The step that matters
Folding in the beaten egg whites. Whipped whites hold the air that lightens the cake. Stirring them in vigorously knocks out that air, so fold gently and keep the batter airy.
Swap the currant
How well each one fits the dish's main ingredients (flour, sugar, butter, egg, milk):
- Vanillafits better
- Raisinfits better
- Figfits better
- Currantthe original
Fit is the average pairing score against flour, sugar, butter, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
