Frozen Chinese dumplings ready to heat are not new, especially in grocery stores in Chinese neighborhoods, but two Manhattan restaurants now sell them for pickup or delivery. Northern Tiger, the counter-style spot at Hudson Eats in Brookfield Place near the World Trade Center, has introduced kits of dumplings now being made at Wayla, their sibling restaurant. The dumplings are to be boiled, then pan fried and served with accompanying sauces. The wrappers are parchment-thin and the fillings like chicken and wood ear mushrooms, tasty. Another restaurant, 3 Times, with locations on the Lower East Side and near Union Square, offers more than a dozen different frozen dumplings, including Shanghai soup dumplings, less common pork and rice dumplings wrapped in leaves, and crunchy little radish pancakes, all to steam or fry.

Northern Tiger, 25 dumplings with sauces, $23.50, for delivery, Wayla, 100 Forsyth Street (Grand Street), northerntigernyc.com; 3 Times frozen dumplings, $10 to $25, for pickup and delivery from 90 Clinton Street (Delancey Street), and pickup from 818 Broadway (East 12th Street), 3times.com.
