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 ↓
Sultana 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.
Make the batter
Cream the butter and sugar together until light and fluffy.
Sift in the flour, salt, and baking powder.
Add the eggs one at a time and mix in the milk.
Beat the mixture well by hand.
Stir in the sultanas, chopped peel, and grated lemon rind. Mix thoroughly.
Bake
Line a cake tin with buttered paper, using two thicknesses at the bottom.
Bake in a moderate oven at 350°F (175°C) for 1.5 hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the cake together as it bakes.
- Butter
- Creaming with sugar traps air and adds richness and a tender crumb.
- Eggs
- Bind the batter and add structure, moisture and richness.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
- Sugar
- Sweetens the cake and helps create a light, aerated batter when creamed.
- Sultanas
- Add chewy pockets of sweetness throughout the cake.
The step that matters
Creaming the butter and sugar. Beating until light and fluffy incorporates air bubbles that expand in the oven and give the cake its lift. Under-creamed butter leaves a dense, heavy crumb.
