From the Super Mario Wiki
Dried Pasta is a type of pasta in Paper Mario that restores three HP and two FP. This inexpensive item's main purpose is as a base ingredient for some of Tayce T.'s recipes, though with most other ingredients, it only creates a Bland Meal. It can be bought at Dry Dry Outpost and doesn't sell well anywhere. It is replaced by the item Fresh Pasta in Paper Mario: The Thousand-Year Door.
