Golden Tuber
I really feel like they have a fine dining aspect. I wasn't able to bring one to the library with me, as unfortunate as that is.
Golden Tubers are a mutation of the regular yellow potatoes. They are often called Golden or Gilded Tubers depending on the area you see them in. This particular food ingredient is not actually made out of god, it just looks like it is. This mutation has a 1 in 100,000 chance of happening. This luxurious item is often sold to royalty and nobility at a very high price point. This potato can elevate any dish just by being in it. When a commoner finds one in their crop, they either sell it or they keep it a secret and put it in what’s known as Rainbow Soup.
Gold potato! :) I would definitely sell it if it came up in my crop, especially if it didn't taste any different.
