I'm allergic to peeling cooked shrimps/prawns... My skin gets itchy and looks like i've been bitten by mosquitoes. I have to de-shell them using fork and spoon or knife, if my husband is around, he does this for me. Funny thing is I have no problem peeling raw shrimps/prawns...i can't do this all the time though because my family prefers them cooked with shell on.
