Ingredients:

  • 3 Tbsp Unsalted Butter (for melting)
  • 1/2 cup All-Purpose Flour (60g)
  • 3 Large Eggs
  • 1/2 cup Whole Milk
  • 1 Tbsp Granulated Sugar
  • 1/4 tsp Salt

Instructions:

  1. Place a 10-inch cast iron skillet in the middle rack of the oven. Preheat the oven to 425°F (220°C) and let the pan heat up for at least 15 minutes.
  2. Combine all batter ingredients (flour, eggs, milk, sugar, and salt) into a blender. Blend on medium speed for 30 seconds until completely smooth.
  3. Pour the batter into a bowl, cover, and let it rest at room temperature for a minimum of 30 minutes.
  4. Carefully remove the screaming-hot skillet from the oven. Immediately add the 3 tablespoons of butter and swirl quickly to coat the bottom and sides as the butter melts and foams.
  5. Immediately pour the rested batter directly over the melted butter in the hot pan.
  6. Return the skillet swiftly to the hot oven. Do not open the oven door for the first 15 minutes of baking.
  7. After 15 minutes, reduce the heat to 375°F (190°C) and bake for another 5–10 minutes, or until the edges are deeply golden brown and crisp.
  8. Serve immediately from the skillet, dusted liberally with icing sugar or dressed with lemon juice.
