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 ↓
To Make a Full Good Plain Cake
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dry mix
Preheat the oven to 400°F (200°C).
In a bowl, mix the flour, baking powder, salt, and spice.
Rub in the butter until the mixture resembles breadcrumbs.
Stir in the sugar, sultanas, currants, and candied peel.
Make the batter
In a separate bowl, beat the eggs and milk together.
Moisten the dry mixture with the egg and milk mixture.
Bake
Pour the batter into a greased cake pan and bake thoroughly in the preheated oven.

Flour and butter barely smell alike, yet cooks put them together in 124,287 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
- All-purpose flour
- Provides the starch and gluten network that gives the cake its structure.
- Baking powder
- Releases gas in the batter so the cake rises and becomes light.
- Butter
- Coats flour particles and adds fat for a tender, crumbly texture.
- Eggs
- Add structure as they set and help bind the batter together.
- Milk
- Adds moisture that hydrates the flour and softens the crumb.
- Granulated sugar
- Adds sweetness and helps keep the crumb tender and moist.
The step that matters
Moistening the dry mixture. Stir only until the liquid is evenly combined. Overmixing develops gluten in the flour, which makes the cake tough and dense rather than light.
Swap the currant
How well each one fits the dish's main ingredients (flour, nutmeg, sugar, butter, egg, milk):
- Vanillafits better

- Figfits better
- Currantthe original
Fit is the average pairing score against flour, nutmeg, sugar, butter, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
