Fresh Lemon-Blueberry Dutch Baby

Ingredients

• 4 tablespoons butter, divided
• 1/2 cup (125 g) whole or 2% milk
• 1/2 cup (64 grams) all-purpose flour
• 4 large eggs
• 3 tablespoons (43 g) granulated sugar
• 1 teaspoon vanilla
• 1/4 teaspoon salt
• the zest of one lemon
• 1 cup (154 g) blueberries
• Confectioners sugar for dusting

Method

1. Place an oven rack in the middle position and preheat the oven to 450°F. Place a 9- or 10-inch cast iron skillet over low heat on your stovetop. Keep it over low heat while you prepare the batter.
2. Melt two tablespoons of the butter in a small skillet, then transfer to a blender. Add the milk, flour, eggs, granulated sugar, vanilla, salt, and lemon zest, and blend until smooth. (Do not skip this step — the batter will be lumpy if you do.)
3. Place the remaining 2 tablespoons of butter into the cast iron skillet. Turn the heat up to medium-high. Let the butter melt, add the blueberries, and give the skillet a shake. Immediately pour the batter over the blueberries and transfer the skillet to the oven. Bake until the pancake is puffed and golden, about 15 minutes.
4. Remove pan from the oven, and dust with confectioners sugar, if you wish. Cut and serve immediately with maple syrup.
