In a mixing bowl, rub together the sugar and lemon zest with your fingers. This helps the oils in the zest to come out and maximise its flavour.
Add in the dry ingredients and mix well. Follow by the wet ingredients plus the blueberries and again, mix well.
In a pan over medium heat, melt some butter and pour in ~1/2 cup of batter. Wait until the edges are cooked and the surface is bubbly, then flip to cook the other side.
Top with butter, maple syrup and more blueberries. Serve
