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 brisk oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Preheat the oven to 400°F (200°C).
In a bowl, mix the flour, powdered sugar, butter, and baking powder.
In a separate bowl, beat the eggs and then combine with the dry mixture.
Add milk if the mixture is too thick.
Bake and roll
Roll out the dough very thin on a floured surface.
Bake on a baking sheet for 10 minutes.
Spread jam over the baked dough and roll it up.
Serve with boiled custard.

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 structure that holds the dough together when rolled.
- Eggs
- Bind the dough and add richness and structure as they set in the oven.
- Butter
- Adds fat that gives the baked dough tenderness and flavour.
- Baking powder
- Releases gas during baking so the dough rises and lightens.
- Powdered sugar
- Adds sweetness and a fine texture that dissolves easily into the batter.
- Jam
- Adds sweetness and moisture to the filling spread over the baked dough.
The step that matters
Roll the dough very thin. A thin sheet bakes through quickly and stays flexible enough to roll up with jam. Thick dough can stay doughy in the centre and crack when rolled.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
