In a blender, blend the eggs and egg white until frothy. Add the milk, flour, 2 tablespoons of the melted butter, sugar, vanilla and salt and blend just until smooth. Using a spatula, scrape down the sides of the blender. Add the orange zest and pulse just to combine.
In a cast-iron skillet over medium heat, heat remaining 2 tablespoons butter. Once hot, pour in the pancake mixture and transfer to the oven. Cook until golden brown and puffy, about 20 minutes.
Top with powdered sugar. Slice and serve with Strawberry-Mint Compote and Blood Orange Maple Syrup.
Place the strawberries, orange juice, honey and orange peel in a small saucepan over medium-low heat. Cook, stirring occasionally, until the strawberries are soft, about 8 minutes. Remove the orange peel. Stir in the mint. Serve warm or cold.
Blood Orange Maple Syrup:
Stir the blood orange juice and maple syrup together in a small bowl. Set aside.
