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 ↓

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
Preheat the oven to 400°F (200°C).
Rub the butter into the flour.
Make the dough
Add the sugar, coconut, and beaten eggs.
Mix and add just enough milk to hold the mixture together.
Shape and bake
Place small lumps on a floured baking sheet.
Bake in the preheated oven.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fine wholemeal flour
- Provides the main structure that the dough sets around when baked.
- Butter
- Coats the flour particles and adds fat for a tender, crumbly texture.
- Eggs
- Bind the mixture and help set the structure as it bakes.
- Caster sugar
- Adds sweetness and helps the surface brown during baking.
- Desiccated coconut
- Adds chewy texture and a distinct coconut flavour.
- Milk
- Moistens the dry ingredients so they hold together as a dough.
The step that matters
Add just enough milk. Too little milk leaves the mixture crumbly and unable to hold its shape, while too much makes the dough sticky and spreads it out during baking. Adding it gradually lets you stop once the mixture just holds together.
Swap the coconut
How well each one fits the dish's main ingredients (flour, butter, egg, milk, sugar):
- Vanillafits better
- Raisinfits better
- Figfits about as well
- Coconutthe original
Fit is the average pairing score against flour, butter, egg, milk, sugar. Candidates are from the same food group and used in at least 100 recipes.
