Though these dumplings are traditionally cooked in stacked Asian bamboo or metal steamers, you can also use a pasta pot with a deep perforated colander-steamer insert. If your pot has a second shallow colander-steamer insert, you can steam 2 batches at once. The dumplings should be served warm, so reheat them in batches as platters need replenishing.
·Dumplings (without sesame seeds) can be formed and steamed 1 day ahead and cooled completely, then chilled, covered. Steamed dumplings can also be frozen 1 week; freeze in 1 layer on a plastic-wrapped tray until hardened, then transfer to a sealable plastic bag. Reheat (do not thaw if frozen) in colander-steamer insert over simmering water (over low heat) until heated through, about 6 minutes.

Ingredients
Preparation

Assemble dumplings:
Step 2
Separate wonton wrappers and restack in piles of 10. Cut through each stack with cookie cutter and discard trimmings. Arrange 6 rounds on a work surface (keep remaining rounds covered with plastic wrap) and mound a scant tablespoon filling in center of each. Lightly moisten edge of wrappers with a finger dipped in water. Working with 1 at a time and leaving dumpling on flat surface, gather edge of wrapper around side of filling, pleating wrapper to form a cup and pressing pleats against filling (leave dumpling open at top). Flatten filling flush with edge of wrapper with wet finger and transfer dumpling to a tray. Make more dumplings in same manner with remaining rounds and filling.
Steam dumplings:
Step 3
Generously oil bottom of colander-steamer insert and bring a few inches of water to a boil in pot so that bottom of insert sits above water. Arrange 10 dumplings, about 1/2 inch apart, in insert and steam over moderate heat, covered, until dough is translucent and filling is just cooked through, about 6 minutes.
Step 4
Stir together black and white sesame seeds and sprinkle over dumplings. Serve immediately.
