I have asked my fish monger about deveining the shrimp but leaving the shells on and he said it isn't possible. I've tried to do it but I was not successful. Does anyone have a good way to remove the vein but leave the shell on? Is it really so horrible to serve them without removing the vein? And, yes, I know that the vein is the shrimp's digestive tract.
(Oh, and $10 off your order of $50 or more in the Food52 Shop, too.)
