Why it works: Onion and potato 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 gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the dough
In a bowl, mix flour and lard (or suet) with enough cold water to form a dough.
Fill and shape
Cut the meat into small pieces.
Roll out the dough and place the meat in the center.
Season with salt and pepper, and add the chopped onion.
If desired, add the sliced potato.
Fold the dough over to form a turnover and seal the edges.
Bake
Bake in a preheated oven at 400°F (200°C) for one hour.

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 dough that encloses the filling.
- Lard or suet
- Adds fat that makes the pastry tender and flaky.
- Meat
- Provides the main savoury filling that cooks through inside the pastry.
- Onion
- Adds moisture and aroma as it softens inside the filling.
- Potato
- Adds starch and body to the filling when included.
The step that matters
Sealing the edges. A tight seal keeps juices and steam inside the pastry during baking. A weak seal lets the filling leak out and the pastry dry or burn at the seam.
Swap the potato
The recipe marks potato as optional. How well each one fits the dish's main ingredients (flour, meat, pepper, onion):
- Okrafits about as well
- Shallotfits about as well
- Turnipfits about as well
- Potatothe original
Fit is the average pairing score against flour, meat, pepper, onion. Candidates are from the same food group and used in at least 100 recipes.
