Why it works: Flour and milk are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
A Good Plain 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).
Make the batter
In a large bowl, mix together the flour, baking powder, salt, spice, and sugar.
Rub in the margarine until well combined.
Add the sultanas, currants, and candied peel.
In a separate bowl, beat the egg and milk together, then moisten the mixture with it.
Pour the batter into a greased cake pan.
Bake
Bake for about 1 hour or until a toothpick comes out clean.

Flour and milk barely smell alike, yet cooks put them together in 78,219 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Millennium flour
- Provides the main structure that holds the cake together as it bakes.
- Borwick's baking powder
- Releases gas during baking so the cake rises and becomes light.
- Sugar
- Adds sweetness and helps the crust brown during baking.
- Margarine
- Adds fat that tenderises the crumb and carries flavour.
- Egg
- Binds the mixture and adds structure and richness as it sets.
- Sultanas
- Add chewy sweetness and moisture throughout the cake.
The step that matters
Rub in the margarine until well combined. Coating the flour particles with fat limits gluten formation, so the cake stays tender rather than tough. Leaving lumps of fat or uneven mixing can cause a dense or uneven texture.
Swap the currant
How well each one fits the dish's main ingredients (flour, sugar, egg, milk):
- Vanillafits better
- Raisinfits better
- Figfits better
- Currantthe original
Fit is the average pairing score against flour, sugar, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
