Something about pre-shelled pistachios ruins the "ceremony" for me. Killer convenience for the pistachio brittle I make every christmas though.
I grab a bag or two of the XX-hot red on my way to the airport when I'm going to the UK for business. They really dig these over there and I kind of like them too...
