Wash and dry the blueberries. If using frozen, don't wash them. Take 1 tablespoon of flour and lightly coat the blueberries in the flour.
Separate the eggs. Put egg whites in a medium bowl and egg yolks in a large bowl.
Mix the egg whites until stiff peaks form.
Add the fresh ricotta, milk, lemon zest, lemon juice to the egg yolks in their bowl and mix until really well combined.
Sift the dry ingredients directly over the wet ingredients. This includes the flour, sugar, baking powder and salt.
Gently fold the dry ingredients into the wet ingredients. Don't over mix.
Gently fold in the blueberries and then the whipped egg whites into the mixture. Again, don't over mix.
Heat your large skillet on medium heat and lightly oil with a little bit of olive oil or a little butter.
Take about 1/4 cup of pancake batter and place on the hot skillet.
Once little bubbles form on top, it's time to flip and cook the other side for about 1-2 minutes. (Lower temperature to medium-low heat so the pancakes don't burn.)
