                    Try another citrus in this recipe, such as fresh lime zest and juice, or even lime- or citrus-flavored vodka. (You may need a little extra sugar, because it isn't naturally as sweet as limoncello liqueur.) Ingredients: 
                    
                        
                                                1/2 cup sugar  |  
                                                1 tablespoon lemon zest  |  
                                                3 cups ice cubes  |  
                                                1/2 cup fresh lemon juice  |  
                                                1/2 cup limoncello liqueur (optional)  |  
                                                garnish: lemon slices  |  
                                                
                     
                    Directions: 
                    
                        
                            
                                1. Combine sugar and 1/2 cup water in a small saucepan, and cook over medium heat, stirring often, 3 minutes or until sugar dissolves. Remove pan from heat; stir in lemon zest. Let cool to room temperature, about 30 minutes. 2. Strain mixture through a fine wire-mesh sieve into a blender, pressing solids with a wooden spoon to extract liquid. Discard solids. 3. Add ice cubes, lemon juice, and limoncello, if desired, to blender and process until smooth and slushy. Garnish, if desired. Serve immediately.                              |
