In a small saucepan, warm the butter until it melts. Set the pan aside to cool a bit.
Mix the flour and salt together.
Pour in the milk, then the eggs. And mix.
When you’re ready to rock ‘n roll, add a little butter to the hot non-stick pan. With a ladle or large spoon, add two generous Tbsp of batter to the pan. Quickly, use the bottom of the ladle to spread the batter to the edges.
As soon as the batter loses its sheen and the edges just begin to brown (30 seconds to a minute, depending on how hot the pan is), flip the pancake with a spatula. The second side will cook very quickly, not even half the time as the first side.
Remove to a plate and cover with wax paper.
Repeat with the remaining batter, adding more butter to the pan as necessary.
Use immediately or refrigerate, layered with wax paper.
