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 ↓
Potatoe Pasty
Ingredients
Directions
The book says “a slow oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the filling
Boil, peel, and mash the potatoes until smooth.
Mix the mashed potatoes with salt, pepper, and butter.
Assemble and bake
Roll out the pie crust thinly.
Place the potato mixture on one half of the crust.
Fold the other half over and pinch the edges to seal.
Bake in a moderate oven at 350°F (175°C) until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the bulk of the filling, giving a soft, moist texture when mashed smooth.
- Butter
- Adds fat and richness, softening the mashed potato and carrying flavor.
- Pie crust
- Encloses the filling and browns in the oven to form a golden, sealed pastry.
The step that matters
Pinch the edges to seal. If the edges are not sealed firmly, filling can leak out during baking and the pasty can open. A tight seal keeps the moist potato inside so it cooks through and the crust browns evenly.
Swap the potato
How well each one fits the dish's main ingredients (pepper, butter):
- Capsicumfits better
- Potatothe original
- Carrotfits less well
- Onionfits less well
Fit is the average pairing score against pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
