Preheat the oven to 450 degrees F (230 degrees C). Grease and flour six 6-ounce custard cups.
Beat eggs slightly in a medium bowl. Beat in flour, milk, and salt until just smooth; being careful not to overbeat.
Fill custard cups ½ full.
Bake in the preheated oven for 20 minutes. Decrease the oven temperature to 350 degrees F (175 degrees C) and bake for 20 minutes more. Immediately remove from cups and serve piping hot.
