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 ↓
Common Mutton Pie
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Preheat the oven to 350°F (175°C).
Butter a pie dish and line it with half the rolled-out paste.
Evenly layer the mutton in the dish.
Sprinkle the mutton with salt and pepper to taste.
Pour in cold water until it's within 1 inch of the rim.
Roll out the remaining paste to cover the pie, about ½ inch thick.
Wet the edges of the paste with cold water or egg white.
Seal the edges tightly to the rim of the dish.
Cut a small slit in the top to allow steam to escape.
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.
