No this isn't a mutant radioactive lemon in my hand, although it could be, it is almost as big as my head. It is a citrus fruit we call Kappat (don't ask I think it's Farsi) fresh from my mother's garden. and no, it doesn't have great lemonade potential because it is practically all peel and kind of dry inside. But the peel can be used to make great marmalade.
