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 ↓
Apple Roly-poly
Ingredients
Directions
Make the dough
Sift the flour, salt, and baking powder together.
Rub in the butter.
Beat the egg and add it to the flour mixture with enough milk to make a soft dough.
Turn the dough out onto a floured surface and knead until smooth.
Roll the dough into a sheet ¼ inch thick.
Fill and roll
Spread the dough thickly with sliced apples.
Sift the sugar and cinnamon over the apples.
Roll the dough like a jelly roll and press the edges together.
Cook and serve
Place the pudding in a baking dish, cover, and steam over boiling water for 1.5 hours, or bake in a pudding dish for 40 minutes.
Serve with lemon or wine sauce.

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 once mixed with liquid.
- Baking powder
- Releases gas during cooking so the dough rises and stays light.
- Butter
- Adds fat that tenderises the dough and keeps it from turning tough.
- Egg
- Binds the dough and adds richness and structure.
- Sugar
- Adds sweetness and helps the filling taste balanced with the apples.
- Apples (in the method)
- Provide moisture and tart flavour that contrasts with the sweet dough.
The step that matters
Rolling the dough and sealing the edges. If the edges are not pressed firmly together, filling can leak out during steaming or baking and the roll can open up. Rolling the dough evenly keeps the layers and filling in a neat, consistent spiral so it cooks through at the same rate.
