These potiates are Venezualan marsupials with sharp claws, big teeth and they are very, very vicious.

So you have to make sure they are properly and not just lightly dead and you should do this by poking them with a stick. If they twitch, just leave them a while longer but watch out for reflex action from their teeth.

Fill in the time by consuming any other purchases you might have made in Green Lanes (fast running may be necessary) and think about ingredients for the marinade.
Garlic, ginger and chilis, finely chopped, and olive oil from somewhere olives are growing nowadays (I think this includes polar regions), or if funds are short, used engine oil will be fine.

Best to use straight away after several hours of marinading, but if required, they can be kept in the freezer. They don't take up much space, especially if they've been spatchcocked first and stacked in a pile behind the frozen peas.
