Place all the products on the table, rinse the berries with cold water, wash the egg.
              
              
 
              
      
     
              
              
               
              
                  
                   
                   
               
              In a deep bowl, prepare a mixture of mascarpone cheese, eggs and sugar.
              
              
 
              
      
     
              
              
               
              
                  
                   
                   
               
              Using an electric mixer, beat the mixture until smooth.
              
              
 
              
      
     
              
              
               
              
                  
                   
                   
               
              The first filler for tartlets is cream.
              
              
 
              
      
     
              
              
               
              
                  
                   
                   
               
              Continue filling the tartlets: place blackberries on top of the cream, then sprinkle the dessert with powdered sugar.
              
              
 
              
      
     
              
              
               
              
                  
               
              To decorate, drizzle the tartlets with chocolate or caramel topping and garnish each serving with fresh mint leaves.
