All varieties of chocolate bars and sweets. OAE Old Antarctic Explorer. Someone who's been around in Antarctica for a while, several summers, or at least a Winter, the more the better of course.
The general term for any type of chocolate or sweets / candy, whether it contains nuts or not. A personal note here, when I first arrived in Antarctica I was most unimpressed with the unhealthiness of the food that people took out with them when leaving base for a day trip - one to three bars of chocolate and nothing else. Being of sterner stuff I promptly made myself some healthy sandwiches (tuna if I remember rightly) - I was observed with interest but without comment by other (as it turned out - wiser) people around. Come lunch break, while others tucked into their hard but edible "nutty" I sat and sucked on a frozen sandwich. Br
