Heat a large non-stick griddle or skillet over medium heat.
In a medium size bowl, mix together flour, sugar, baking powder, baking soda and salt. Stir to combine well.
In a small bowl, mix buttermilk, ricotta cheese, melted butter, egg and lemon juice/ zest.
Stir the wet ingredients into the dry ingredients until combined but slightly lumpy.
Coat griddle or skillet with nonstick cooking spray and pour 1/4 cup of batter on the griddle. Cook for 2 to 3 minutes per side or until pancakes are golden and cooked through. Repeat with remaining batter.
Serve the pancakes warm topped with blackberries and syrup.
