I was at the Pirate Festival at Fort York in Toronto last year, and I was really disappointed by the food on offer. Basically, there were hot dogs, hamburgers, and a really ill-conceived "soup in a bread bowl". (Hot soup outdoors in the heat and humidity of August? Blech!)
I remember thinking at the time that recreating a bucanneer's meat-roasting fire really wouldn't have been that difficult for the organizers, and it would have provided much better flavour and period atmosphere.
I always think of cold meat pie, cheese and apples as being a very piratey picnic meal -- one that Ben Gunn & Jim Hawkins would enjoy!
