Curiously my daughter did make one of here friends turn green. The first school day after our first skiing holiday she took sandwiches for lunch. Her friend innocently asked what was in them. Reindeer, and quite nice it was too.
Reindeer is excellent. One of the more accessible variants is "Renskav", literally "Reindeer shavings" which is thinly sliced small pieces of meat, frozen, that typically go in stews and the like; fried, with chopped onion, perhaps some mushrooms, cream added, as is salt, pepper, crushed juniper berries, and then left to simmer.
Serve with mashed potatoes, and lingonberry jam.
Also, smoked reindeer is a treat!
