Add eggs, flour, milk, sugar, vanilla, salt and lemon zest to a blender and blend until smooth.
Place butter in two heavy cast iron skillets (5-6" in width) (or one large skillet) and place in the oven until butter has melted. Pour half the batter into each pan, return them to oven and bake for 20 minutes, until the pancakes are puffed and golden. Lower oven temperature to 300 degrees and bake five minutes longer.
Remove pancakes from oven, serve individually if using mini skillets, or cut larger dutch baby into wedges and top with a spoonful or two of lemon curd and blueberries and a dusting of confectioners sugar. If desired, garnish with lemon slices and a sprig of fresh mint.
