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 ↓
Shrewsbury Cake
Ingredients
Directions
The book says “a sharp oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Preheat the oven to 400°F (200°C).
In a large bowl, mix the flour, eggs, sugar, lemon zest, and butter.
Add just enough milk to form a paste.
Roll out the dough to about 1 inch thick.
Shape and bake
Cut into shapes using a round, diamond, or heart-shaped cutter.
Place the cut shapes on a clean baking sheet.
Bake in the preheated oven until golden.

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
- Flour
- Forms the structure of the dough, holding the cakes together as they bake.
- Eggs
- Add structure and richness, helping the dough bind and set in the oven.
- Butter
- Adds fat that makes the cake tender and rich in texture.
- Sugar
- Adds sweetness and helps the surface brown as it bakes.
The step that matters
Add just enough milk to form a paste. Flour absorbs liquid as it sits, so adding too much milk at once can make the dough sticky and hard to roll, while too little leaves it crumbly. Adding it gradually gives a dough that holds together and rolls cleanly.
Swap the lemon

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