Preheat oven to 450°F (232°C).

Beat eggs with a wire whip until well aerated.

Add milk and whip again until combined.

Add salt and flour to the egg mixture.

Stir with a fork until just blended; avoid overmixing.

Melt butter in a cast-iron skillet or 8x8 inch baking dish with at least 2-inch sides.

Ensure the butter coats the bottom and sides of the pan.

Pour the batter into the prepared pan.

Bake in the preheated oven for 15 minutes, or until golden brown and puffed up.

Serve immediately with butter, syrup, and powdered sugar.

Optionally, sprinkle with lemon juice or top with fresh fruit (blueberries, peaches, apples, or mixed berries).
