This is actually pretty simple to make (a bit time consuming).  Using cast iron pan to pan fry is actually not messy and doesn’t need as much oil!  Just need 12 oysters, 1/3 cup of plain all purpose flour, 1 egg and 1/2 japanese bread crumb (panko). Dry the oyster in paper towel, season lightly with salt and pepper, the dip into flour then shake off the excess flour, wait until the flour coating becoming damp and dip into flour again. Dip into lightly beaten egg and finally dip in panko and it is ready for frying. I found just a couple minutes on each side is just right amount of time.
