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 hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the filling
Cut the beef and potatoes into small dice.
In a saucepan, combine the meat, potatoes, chopped onion, cold water, and seasonings.
Stew gently until tender.
Make the pastry
Prepare the pastry by mixing flour, fat, and baking powder.
Roll out the pastry and cut into rounds about the size of a saucer.
Assemble and bake
Place a spoonful of the prepared mixture in the center of each round.
Wet the edges, fold one half of the pastry over to enclose the filling, and pinch the edges to seal.
Bake in a hot oven at 400°F (200°C) for about 1 hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef steak
- Provides the main filling, becoming tender through slow stewing.
- Potatoes
- Add bulk and moisture to the filling as they soften during stewing.
- Flour
- Forms the structure of the pastry that encloses the filling.
- Fat
- Makes the pastry tender and flaky by coating the flour particles.
- Baking powder
- Helps the pastry rise slightly and lighten its texture in the oven.
The step that matters
Pinching the edges to seal. A tight seal keeps juices inside the pastry while baking; a weak seal lets filling leak out and can leave the pasty dry and the crimp burnt.
