Why it works: Potato and onion are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the pastry
Roll out the pastry to ¼ inch thick and cut into large rounds with a round cutter.
Make the filling
Cut the meat and potatoes into small dice, season with salt and pepper, and mix with the chopped onion.
Place equal amounts of the mixture in the center of each pastry round.
Shape and bake
Wet the edges of the pastry, fold it over to enclose the filling, and crimp the edges to seal.
Brush the pasties with beaten egg and place them on a greased baking sheet.
Bake in a moderate oven at 350°F (175°C) for about 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Plain short pastry
- Forms an enclosing crust that holds the filling and bakes into a crisp, golden shell.
- Beef steak
- Provides the main filling, cooking through as the pasty bakes to become tender and savory.
- Potatoes
- Add bulk and moisture to the filling, cooking through in the enclosed pastry.
- Onion
- Adds aroma and sweetness as it softens and flavors the filling during baking.
The step that matters
Crimping the edges to seal. If the edges are not wetted and firmly crimped, the pastry can open during baking, letting juices escape and leaving the filling dry and the crust underbaked.
