No extra water is needed for preservation. If using chunky Parmesan, grate it finely ahead of time.
              
              
 
              
      
     
              
              
               
              
                  
                   
                   
               
              Prepare classic pesto sauce. Place basil leaves, garlic, 3/4 of the pine nuts, and half of the Parmesan cheese into a chopper or blender. Add olive oil and puree until smooth.
              
              
 
              
      
     
              
              
               
              
                  
                   
                   
               
              Make homemade preserves. Place the finished pesto sauce in a saucepan and place on the stove. Add remaining cheese and pine nuts. Bring to a boil over medium heat. Continue simmering the pesto for another 5 minutes. Transfer to sterile jars and seal.
              
              
 
              
      
     
              
              
               
              
                  
                   
                   
               
              Store the pesto prepared according to the recipe for the winter in the refrigerator or in a cool place.
