As part of Lucky Peach’s new “People Cooking Things” series, legendary Chinese chef Martin Yan and Koi Palace’s chef Chen show how to make classic shrimp dumplings — or har gow. Yan, of course, makes all other cooking-tutorial videos seem dull: He rolls and flattens dough with rampant enthusiasm, and instructs how to expertly push and pleat once the stuffing’s inside, shouting, “Push! Pleat! Push! Pleat!” over and over.
