Preheat a griddle or frying pan on medium-low heat.
Begin by beating egg whites until soft peak forms and set aside.
In a large bowl, mix together the egg yolks, ricotta, zest and juice of the lemon, the oil, and the sugar.
In a separate bowl add flour, baking powder, salt, and poppy seeds and mix.
Add the flour mixture to the wet mixture.
Once combined, fold in the egg whites until just mixed (try not to deflate the egg whites).
Lightly grease the griddle or frying pan. Add the pancake batter in 1/3-1/2 cup scoops and gently spread to flatten.
Cook on the first side until the bottom is golden brown. Flip and repeat on the second side.
