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 ↓
Mutton Pie
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 400°F (200°C).
Butter a pie dish and line it with half of the rolled‑out pastry.
Evenly layer the mutton in the dish.
Sprinkle the mutton with salt and pepper to taste.
Pour cold water into the dish until it’s an inch from the top.
Assemble and bake
Roll out the remaining pastry to cover the pie, about ½ inch thick.
Wet the edges of the pastry with cold water or egg white and seal securely.
Trim the edges close to the rim of the dish and cut a small slit in the center.
Bake the pie for 1 hour and 15 minutes.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Forms the structure of the pastry that encloses the filling.
- Butter or suet
- Adds fat that makes the pastry tender and rich.
- Mutton
- Provides the meat filling that cooks slowly in the pie.
- Cold water
- Adds moisture to the filling and helps bind the pastry edges.
The step that matters
Sealing the pastry edges. A tight seal keeps the juices and steam inside the pie while it bakes. Gaps let the liquid escape, which can leave the filling dry and the pastry underbaked at the rim.
“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.
