Disclaimer: this is a dumbed down question just for fun, an opposition to the hardcoe "dumbing down" threads.
Let's say a Khajiit trader is going to make a Tamriel-Earth food&drink transport and you are one of the fortunate customers that can order 1 meal only, food and/or drink. What is it that one special product you would like to taste from Tamriel's gastronomy, as known from the games and books?
ps: no, potions of invisibility are not food and can't be transported
ps2: don't push lists on the poor trader, just 1 food 1 drink per person, storage capacity limited, no feather potions, many highwaymen on the road
Bon appetit!
