This (below) is what i read on another website, but i wondered what to do with a baked potato. Just food, or an item needed for something else?

INCA
Oh! Vase
Location: Village, 3rd house up on the west side of building
Talk to the waremaker and find out what he needs. Exit and go inside the door 2 doors down, in the top right corner open the chest to get Gold Foil item. Go back to the waremaker with this, 10 yellow clay and 5 dry clay.
Reward: Baked potato
