Dumplings of the World
Wrap a filling in dough and cook it: almost every country does, and each one argues about the pleats. China boiled them, Japan pan-fried them, Poland stuffed them with potato and cheese, and America renamed them Peking ravioli and put cream cheese in a wonton. Here is every style, step by step.

Jiaozi (Boiled Pork and Napa Cabbage Dumplings)
Hand-rolled wheat wrappers pleated around a silky filling of ground pork, blanched napa cabbage, Shaoxing wine and sesame oil, boiled in a big pot and served with black vinegar and soy sauce for dipping.

Gyoza (Japanese Pan-Fried Pork and Cabbage Dumplings)
Thin store-bought wrappers pleated around pork, salted cabbage, shiitake, garlic and ginger, browned on one side, steamed under a lid and crisped with sesame oil, with a soy, rice vinegar and chili oil dip.

Kimchi Mandu (Korean King-Size Kimchi Dumplings)

Khinkali (Georgian Soup Dumplings)
Big pleated dumplings twisted into a knot at the top, filled with beef and pork loosened with stock and butter and spiced with cilantro, chile, caraway, coriander and cumin, boiled so the filling turns to broth inside, then eaten by hand with black pepper.

Pittsburgh Potato-Cheddar Pierogi with Butter and Onions
Tender sour cream dough wrapped around smooth mashed russets with sharp cheddar and butter, boiled and tossed in a skillet of onions caramelized in butter, the way western Pennsylvania serves them.

Browned chicken thighs and breasts simmered in broth with onion, thyme and bay, then flat strips of rolled chicken-fat dough cooked right in the pot and the broth thickened with toasted flour, finished with shredded chicken and parsley.

Crispy Lace Frozen Dumplings (Skillet Potstickers with a Golden Skirt)
A bag of frozen pork potstickers browned in a nonstick skillet, steamed under a thin flour-and-water slurry that fries into one lacy golden skirt, flipped onto a plate and served with soy sauce, sesame oil and chile flakes, in 25 minutes.

Takeout-Style Crab Rangoon (Fried Cream Cheese Wontons)
