my ideas for dunmeri cuisine:
>the south and mainland uses more rice. water is more plentiful and saltrice does require a lot, though the strange wild grain was originally found to grow even in water with a high salinity, making it perfect for even saltwater marshes
>northern vvardenfell tends to use a lot more wickwheat. some nobles on the mainland see wickwheat as the grain of choice for the poor ashlander nomads, and thus will turn up their noses at it. it most closely resembles farro, and it isn't too hard to cultivate but it grows like weeds in the grazelands
>ash yams are very popular, but also still more commonly eaten on vvardenfell where the high amount of ash makes them easy to grow. its not uncommon for the people of vvardenfell to use it to make fillings or flatbreads
>stews and stuffed veggies are staple main dishes usually served with a salad and some kind of bread and sauces. each region shows great variation though, and even tremendous variation within a region depending on the houses and families living there. despite seeming very similar, you'll be surprised at just how different dishes can be
>noodles arent a staple food, but theyre also not uncommon. typically eaten for lunch, and can be made from grains or even starch. stir fried glass noddles and veggies are very common in various places in morrowind, with everything from a sweet a savory taste to super spicy.
>meat and game are more reliable food sources in northern vvardenfell, and thus you'll find cuisines of ashlanders, ald ruhn, and other northern vvardenfell towns (and in the first era, house dagoth) to rely more heavily on it. the constant ash storms means its sometimes easier to rely on meat of nix hounds, nix oxes, and guar than trying to grow things reliably. this is a point of contention as many southern nobles see the meat heavy dishes as crude and unsophisticated.
>kwama eggs are another common food you'll find across morrowind in everything from savory foods to sweets. kwama egg starts, preserved kwama eggs on congee/poridge, and more. sometimes they'll be wrapped with ground meat, breaded, and deep fried with a blend of dunmeri spices and the rich yolk oozing out, especially popular in dunmeri taverns outside of morrowind.
