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 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.
Prepare the dry ingredients
Mix the flour and baking powder, then sift into a bowl.
Rub in the butter and add the sugar.
Rinse the sultanas in a sieve.
Sprinkle the sultanas with a little flour and rub gently to remove dirt and stalks.
Pick over the sultanas and add them to the dry ingredients along with the candied peel.
Make the dough
Beat the egg.
Mix in nearly all the milk.
Combine everything into a stiff dough, adding more milk if needed.
Bake and finish
Bake in a well-greased cake tin lined with buttered paper at 350°F (175°C) for about one hour.
Once done, remove from the tin and take off the paper.
Cool on a sieve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the structure of the cake once mixed with liquid and baked.
- Baking powder
- Releases gas during baking so the cake rises and becomes lighter.
- Egg
- Binds the dough and adds richness and structure to the crumb.
- Butter or dripping
- Rubbed into the flour to add fat, tenderness and flavour.
- Milk
- Adds moisture so the flour hydrates and the dough comes together.
- Sultanas
- Add chewy pockets of sweetness and fruit flavour throughout the cake.
The step that matters
Adding milk to the dough. Flour absorbs liquid at different rates, so the dough can end up too stiff or too wet. Adding milk gradually and checking the texture keeps the crumb tender rather than dry or heavy.
“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.
