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

Oven, in the book's wordsA slow oven

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

  1. Boil, peel, and mash the potatoes until smooth.

  2. Mix the mashed potatoes with salt, pepper, and butter.

Make and fill the pastry

  1. Make a dough by mixing flour with enough water to form a paste.

  2. Roll out the dough thinly like a large puff pastry.

  3. Place the potato mixture in the center, fold the dough over, and pinch the edges to seal.

Bake

  1. Bake in a moderate oven at 350°F (175°C) until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Potatoes
Form the soft, moist filling that gives the pasty its body.
Butter
Adds fat and richness to the mashed potato filling.
All-purpose flour
Forms the dough structure that encloses the filling and sets when baked.

The step that matters

Pinch the edges to seal. If the edges are not sealed firmly, the filling can leak out during baking and the pasty may open or dry out. A tight seal keeps the moist potato filling contained while the dough cooks.

Swap the potato

How well each one fits the dish's main ingredients (pepper, butter, flour):

  1. Shallotfits better
  2. Chivefits about as well
  3. Capsicumfits about as well
  4. Potatothe original

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