Why it works: Potato and pepper are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 8,305 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Mash the cold boiled potatoes thoroughly.
Add coarse sea salt, butter, and enough flour to make a paste that can be rolled out.
Roll out the paste evenly and cut it into squares, similar in size to sausage roll pastry.
Fill and bake
Place some chopped and seasoned meat in the center of each square.
Fold the squares over and glaze with the egg white.
Bake in a 400°F (200°C) oven until nicely browned.
Serve hot.

Butter and flour 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
- Cold boiled potatoes
- Provide the starchy base that binds the dough into a rollable paste.
- Butter
- Adds fat for richness and a tender texture in the pastry.
- Egg white
- Glazes the pastry so it browns and turns glossy in the oven.
- Flour
- Gives the paste enough structure to roll out and hold its filling.
- Tinned meat
- Forms the savoury filling sealed inside each pastry square.
The step that matters
Glazing with egg white before baking. A thin, even egg white glaze promotes browning and a glossy finish. Brushing too heavily can pool and make the surface sticky, so apply it lightly and evenly over the folded edges.

Fit is the average pairing score against meat, butter, egg, pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
