If you haven’t already answered this, do you have any theories on what kind of food our Atmoran forefathers would’ve eaten in times of old?
There is little we know about Atmora, but from what we do know, I can make a few deductions about the Atmorans diet. Seafarers by trade, there is no indication that the Atmorans pursued any agricultural activity whatsoever, relying on hunting instead. As such, there wouldn't be anything in the way of milk products, so foods like cheese, skyr, and yoghurt would not be viable.
What food was available would therefore be based on the geography. The Atmoran Frostwood, which served as a bountiful hunting ground in the midst of the frozen island, would be where most of their food was gathered and hunted. Atmora also purportedly has marshes to the east, somewhat akin to the lands around Morthal. The running streams and rivers also give us a clue as to the sort of fish they ate.
Fish, fowl, and game of all sorts would have been consumed. Whether it was salmon from the rivers, venison or aurochs, mudcrab and slaughterfish, the food that the Atmorans ate would not necessarily be entirely dissimilar to ours. In terms of vegetables, they would have foraged wild greens of all sorts, peas, beans, mushrooms, and even wild garlic for flavouring. In terms of seasonings, you'd find salt from the Sea of Ghosts, various herbs, as well as the dried, pulverised kelp that's sprinkled into food in Winterhold to this day.
Mead was not a drink the ancient Atmorans would be familiar with, due to the need for beekeeping and the inhospitable climate that prevents it. Liqueur would instead come in the form of fermented snowberries or juniper berries, which grow in harsh climates like Atmora; I am personally trying to develop a brew based on ancient traditions.
Based on what we know then, a traditional Atmoran meal would include dishes like smoked trout stuffed with thyme and wild garlic, sautéed mushrooms with salted bristleback bacon, horker roast with baked pears, fried whitebait in a seagull egg omelette, and even hazelnut-and-snowberry tart made with a crust of sliced apples. ~Talviel
