Why it works: Potato and onion 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 ↓
Cold Meat Rolls
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 filling
Chop the cooked meat and onion very finely.
Season with pepper and salt.
Make the dough
Mash the potatoes smoothly.
Add 2 tablespoons of melted butter.
Whisk over low heat to dry.
Turn the mixture onto a table.
Add enough flour to form a dough.
Shape and cook
Roll the potato dough to about ¼ inch thick and cut into 6-inch squares.
Place a spoonful of the chopped meat on each square.
Wet the edges and fold the dough over to seal.
Place the rolls on a greased baking sheet.
Bake at 400°F (200°C) until light brown, or fry in hot fat.

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
- Cooked potatoes
- Mashed to form the dough that encloses the filling.
- Butter
- Adds richness and fat, keeping the dough tender.
- Flour
- Binds the mashed potato into a dough that holds its shape.
- Cooked meat
- Forms the savoury filling inside each roll.
- Onion
- Adds aroma and flavour to the meat filling.
The step that matters
Add enough flour to form a dough. Too little flour leaves the potato mixture too wet to roll and seal, while too much makes the dough dense and tough. Add it gradually until the dough just holds together.
Swap the onion
How well each one fits the dish's main ingredients (meat, butter, potato, flour, pepper):
- Chivefits better

- Asparagusfits about as well
- Onionthe original
Fit is the average pairing score against meat, butter, potato, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
