Why it works: Cheese and butter are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 7,962 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Pierogi II
Ingredients
Directions
Make the dough
Sift and measure flour with salt into a large bowl.
Slightly beat egg with fork, then add egg to flour mixture.
Mix in enough water to make a dough that's soft enough to roll out with a rolling pin but not so dry that it spits and cracks.
Shape the pierogi
Roll out dough on a floured bread board to about the thickness of a cracker.
Use a large rimmed glass or a big biscuit cutter to cut rounds approximately 3–4 inches in diameter.
Fill each round with a generous spoonful of filling, then fold dough in half to make a half-moon.
Pinch and seal the edge of the dough with fingers, then gently fold and pinch edge to make a ruffled edge with about ¼-inch folds.
Boil and fry
Drop each pierogi into a large pot of boiling salted water and boil until they float to the top.
Remove each carefully with a slotted spoon.
Fry the pierogi in a skillet with melted butter until golden brown.
Serve warm or cold.
Nutrition, whole recipe (rough)
Counts 5 of 7 ingredients. The other 2 aren't in our nutrition table and add nothing above, so the real totals are higher.

Flour and butter 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
- All-purpose flour
- Forms the gluten structure that gives the dough its elasticity and shape.
- Egg
- Adds richness and binds the dough, helping it hold together when rolled and filled.
- Butter
- Adds fat and flavor, and browns in the skillet for a golden crust.
The step that matters
Mixing the water into the dough. Too little water leaves the dough dry, so it spits and cracks when rolled; too much makes it sticky. Adding water gradually lets the flour hydrate evenly, giving a dough that is pliable and easy to seal.
