                The classic Japanese egg custard—chawan mushi—is reinvented with creamy corn and crab. Keep an eye on the time while steaming; the custard is delicate and can easily overcook.

Cook corn in a 1-quart saucepan of 
boiling salted water until very tender, 3 to 5 minutes, and drain in a sieve.

Purée milk and hot corn in a blender until almost smooth, then force through a very fine sieve into a bowl, discarding solids. Whisk in egg and salt and divide custard among ramekins.

Steam custards in a steamer set 1 inch above simmering water, covered with lid, until centers are set and a thin knife inserted into center of 1 custard comes out clean, 6 to 8 minutes. Remove ramekins from steamer with tongs and cool custards slightly.
                                         
                                    
                                
                             
                        
                            
                                Make crab topping while custards cool:
                                
                                
                                    
                                        - 
                                            
                                            
Coarsely chop 1/4 cup crabmeat and reserve remainder for another use. Heat butter in a small heavy skillet over moderate heat until foam subsides, then cook crab, stirring constantly, until heated through, about 2 minutes. Stir in chives.
                                         
                                    
                                        - 
                                            
                                            
Serve custards topped with crab.
                                         
                                    
                                
                             
                        
                    
                    Cooks’ note: Custard mixture can be prepared and poured into ramekins 1 day ahead and chilled, surfaces covered with plastic wrap. Bring to room temperature before steaming.
