Making the pancake:
          
            - Place a 9 1/2" (26 cm) iron skillet or stainless steel saucepan in the oven and 
              preheat at 450°F (235°C). The skillet should 
              be very hot when you pour the batter.
            
- Meanwhile, whisk in a bowl:
                  
            - 2 eggs
            
- 1/2 cup milk (120 cc)
            
- a pinch of salt
            
- 1 tablespoon sugar
            
- 1/2 teaspoon vanilla extract
            
- 1/2 teaspoon lemon zest
          
 
- Add and whisk until all the flour is incorporated:
                  
            - 1/2 cup all-purpose flour (70 g)
            
          
 
- Remove the skillet from the oven.  Place 2 tablespoons butter on the 
              skillet and let the butter melt and brown.  Spread the melted 
              butter on the bottom and the side of the skillet. 
          
          
- Pour the batter. 
              Return the skillet to the hot oven and cook for 2 minutes at 450°F (235°C). 
              Lower the temperature to 425°F (215°C) and cook 10 minutes 
              longer. Place the cooked apples and sprinkle powder sugar.
