01 -  In a large bowl, whisk together flour, sugar, baking powder, baking soda, and salt. 
 02 -  In a separate bowl, combine ricotta, egg yolks, milk, lemon zest, lemon juice, and vanilla. Mix until smooth. 
 03 -  Gently stir the wet mixture into the dry ingredients until just combined (do not overmix). 
 04 -  In a clean bowl, beat egg whites to soft peaks using a hand mixer or whisk. 
 05 -  Fold the egg whites into the pancake batter in two additions, being careful not to deflate the batter. 
 06 -  Heat a non-stick skillet or griddle over medium heat and lightly grease with butter or oil. Pour about ¼ cup of batter per pancake onto the skillet. Cook 2–3 minutes per side, or until golden and cooked through. 
 07 -  Serve warm with a generous drizzle of honey and optional fresh berries or powdered sugar.
