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 ↓
Cornish Pasties
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
Peel and boil the onion until tender, then chop it finely.
Chop the meat and potatoes into small pieces.
Assemble the pasties
Roll the short pastry out to about ½ inch thick and cut it into rounds.
Place a little of the meat, onion, and potato on each round, then sprinkle with salt and pepper.
Wet the edges of the pastry, press them together, and create a frill on top.
Insert a knife beneath the frill to allow steam to escape.
Bake
Bake on a greased baking sheet at 400°F (200°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
- Buttock steak
- Provides the meat filling, which becomes tender during baking.
- Parboiled potatoes
- Add bulk and moisture to the filling as they cook through in the oven.
- Short paste
- Forms the sturdy case that holds the filling and bakes to a golden crust.
- Onion
- Adds savoury sweetness and aroma to the filling.
The step that matters
Insert a knife beneath the frill. A vent lets steam escape during baking so pressure does not build inside the sealed pastry and burst the seam or make the filling soggy.
