Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Sausage Rolls
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the filling
In a pot, combine cold meat, flour, butter, gravy, pepper, and salt.
Stir over heat until it boils, then remove from heat and let cool.
Assemble the rolls
Roll out the puff pastry and cut it into squares.
Place some meat mixture on each square, fold over, and pinch the edges to seal.
Glaze the pastry with beaten egg yolk or milk before baking.
Bake
Bake in a hot oven at 400°F (200°C).
If using cooked meat, the rolls are done when the pastry is golden.
If using uncooked meat, bake for 20 to 30 minutes, then move to a cooler part of the oven.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold meat or sausage meat
- Provides the savory filling that forms the body of the rolls.
- Flour
- Thickens the gravy-based filling so it holds together when cooled and wrapped.
- Butter
- Adds richness and fat to the filling, improving flavor and mouthfeel.
- Gravy
- Adds moisture and savory flavor, binding the meat into a spreadable filling.
- Puff pastry
- Creates flaky, layered structure that puffs and browns in the oven.
- Beaten egg yolk or milk
- Gives the pastry a glossy, golden browned surface when brushed on before baking.
The step that matters
Let the filling cool before wrapping. Warm filling melts the butter in the pastry and makes it soggy and slack, so it will not puff and flake well in the oven.
