What foods and drinks would anyone looking into your fictional worlds see as exotic? My Fairy Queen, Roxannadrell, enjoys sampling different foods from various planets and cultures though her own world serves up Griffin Surprise to name one example of what we would consider an exotic food. (Nothing was as surprised as the griffin concerned incidentally).
How is food produced? There is some agriculture on my fictional magical realm and it is felt that freshly produced food is the best. It is also felt magically produced food, though very useful in an emergency, lacks some of the taste and flavour of the same food grown or cooked naturally. It is felt particles from the spell as it is recited gets into the food and spoils it.
