Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Potato Turnovers
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 potato
Mash the hot potatoes and mix in the butter and beaten eggs.
Dust a board with flour.
Spread the potato mixture over the board.
Once cool, cut the potato into 5‑inch round cakes.
Fill and shape
Place a large tablespoon of minced meat on each round.
Fold half of the cake over to cover the meat.
Coat and bake
Coat the turnovers with egg and breadcrumbs.
Bake until golden brown at 400°F (200°C).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the main body of the turnover, setting firm as the mash cools.
- Eggs
- Bind the mashed potato and give the coating a glossy, browned finish.
- Butter
- Adds fat and richness, keeping the mashed potato soft and flavorful.
- Minced meat
- Provides the savory filling that the potato cake encloses.
The step that matters
Cut the cakes only once the potato has cooled. As mashed potato cools, its starch sets and it firms up, so the rounds hold their shape. Cutting while still hot makes the mixture sticky and prone to tearing when folded around the filling.
Swap the potato
How well each one fits the dish's main ingredients (egg, butter, flour, meat):
- Shallotfits better
- Asparagusfits better
- Leekfits better
- Potatothe original
Fit is the average pairing score against egg, butter, flour, meat. Candidates are from the same food group and used in at least 100 recipes.
