Preheat oven to 450 degrees F . Grease and flour* enough cupcake pans: about 1.5 popovers per serving.
In a medium bowl beat eggs slightly, Beat in flour, milk and salt until just smooth; being careful not to overbeat. Fill cupcake pan 1/2 full.
Don't start baking until about 45 minutes before noon.
Bake at 450 degrees F for 20 minutes. Decrease oven temperature to 350 degrees F and bake for 20 minutes more. Immediately remove from cups and serve piping hot.

*Instructions on how to grease and flour: To distribute the flour over the pan, hold one edge of the pan and tap the opposite edge with your free hand. The flour will "skate" over the greased surface and stick to it. When the bottom of the pan is coated, tilt the pan, tapping to move the flour over the sides. Tap out any extra flour into your sink.
