Ramen noodles will be edible for years if stored properly. Ive eaten packages that are over 5 years old, they might taste or smell a bit stale but the MSG packet or some hot sauce covers up just about anything. I am not sure about them loosing their nutrition value, but thats what vitamins are for.

My mom used to make dandelion wine and it was pretty good. You can also make a good tea from the roots.
