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 ↓
Cornish Currant 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).
Mix the flour, salt, and baking powder in a bowl.
Rub in the butter or lard until well combined.
Add the sugar, currants, lemon peel, and nutmeg.
Make and bake
Beat the eggs with the milk and mix into the dry ingredients to form a stiff mixture.
Place the mixture on a floured baking sheet and roll out to about ½ inch thick.
Make several incisions on top with a knife.
Bake for about 40 minutes.
Brush the top with egg white and sprinkle with sugar.

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 as the starches set in the oven.
- Butter or lard
- Coats the flour particles, giving the cake a tender, short crumb.
- Eggs
- Bind the mixture and add richness and structure as they set.
- Baking powder
- Releases gas in the dough, helping the cake rise.
- Castor sugar
- Adds sweetness and helps the top brown as it bakes.
- Milk
- Adds moisture that hydrates the flour and brings the dough together.
The step that matters
Rub in the butter or lard until well combined. The fat must be evenly distributed among the flour particles so it coats them. This limits gluten development and keeps the crumb tender rather than tough.
