                Shrimp toasts are traditionally fried, but our version of this classic Asian appetizer is baked, so your guests won’t have to worry about messy, oily fingers.

Cook garlic and ginger in oil in an 8- to 9-inch heavy skillet over moderate heat, stirring, until softened and fragrant, about 1 minute. Add mirin, soy sauce, and salt (omit salt if making ahead; see cooks’ note, below) and simmer, stirring, 15 seconds. Transfer marinade to a bowl and cool to room temperature.

Add shrimp and cilantro, tossing to coat, and marinate, covered and chilled, 1 hour.

Put oven rack in upper third of oven and preheat oven to 350°F.

Turn bread loaf on its side and evenly cut crust from bottom of loaf using a long serrated knife, discarding crust, then cut a 3/8-inch-thick slice from bottom and trim crust from sides of slice. Put slice on a baking sheet (reserve rest of loaf for another use) and bake, turning over once, until dry but not colored, 8 minutes total. Remove bread from oven but leave on baking sheet.
                                         
                                    
                                        - 
                                            
                                            
Immediately increase oven temperature to 475°F.
                                         
                                    
                                        - 
                                            
                                            
Spread top of hot toast with all of shrimp mixture, packing it down into a thick even layer and covering surface entirely. Make sure oven temperature has reached 475°F, then bake shrimp toast until topping is cooked through, 12 to 15 minutes. Transfer with a large flat spatula to a rack to cool 5 minutes, then transfer to a cutting board.
                                         
                                    
                                        - 
                                            
                                            
Halve shrimp toast crosswise with a very sharp knife, then cut each half lengthwise into fourths, making 8 strips total. Cut each strip into 4 pieces. Serve toasts warm or at room temperature.
                                         
                                    
                                
                             
                        
                    
                    Cooks’ notes: - Mirin is available at Asian markets and some supermarkets.
  - Shrimp can be marinated (without salt in marinade) up to 4 hours. Stir in salt before proceeding.
