Why it works: Flour and egg are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 106,462 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Sausage Rolls
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.
Roll out the puff pastry thinly and cut it into squares about 4 inches.
Remove the skins from the sausages, divide them in half, and roll them in flour.
Place half of the sausage in the center of each pastry square and fold the pastry over.
Cut the ends straight with a knife.
Glaze the tops with egg white and bake in a 400°F (200°C) oven until golden.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.
