Start by separating the eggs into two bowls, one for yolks and one for whites. Combine yolks, milk, ricotta, vanilla, lemon zest, and lemon juice. Stir to incorporate.
In a separate bowl, combine flour, baking soda, baking powder, salt, and sugar. Whisk together. Add the wet mixture you just created to the dry mixture and stir until just combined. Then stir in the melted butter.
Whisk the egg whites until they have stiff peaks and then fold them into the mixture.
On a hot skillet, add ¼ cup of pancake mix. Drop your blueberries onto the pancakes, and flip after 3-4 minutes, or when you have nice big bubbles in the batter. Fry for another 3 minutes and then place on a wire rack to cool. Serve with syrup, butter, and more lemon zest.
Notes
Before you stir in the butter, it needs to be completely cooled.
When combining wet and dry ingredients, mix until just combined. Don't over mix.
Let pancake mix sit for 5 minutes before you add it to the pan to let it rise slightly.
