To celebrate 20 years of campaign, my wife's party is holding a party ingame (its a feast to celebrate the founding of the adventuring party) and a party in real life (because why not).
So they are supposed to bring in foods that should exist in the realms. And the DM is keeping tally of any exceptional ingredients used.
Wife wants to use potatoes and tomatoes (and maybe something else that comes up in the vending booth). Unfortunately they are imports from Maztica and should be damn rare. That is fine, her character is on a quest to obtain rare materials for her cooking.
And to probably sneak in some castings of Alamir's Fundamental Breakdown on some odd cooking from another continent.
What is the availability of Maztica Imports in the Realms? In what regions is it easier to obtain?
Bonus points if there is a price table buried in some book. No matter what edition.
