A Spicy Soup is a recipe in Paper Mario, Paper Mario: The Thousand-Year Door and Super Paper Mario. You can make it by cooking a Fire Flower by Tayce T. and Zess T. or by cooking a Fire Burst by Saffron . It restores 4 HP and FP in the first two games, and restores 8 HP and cures poison in Super Paper Mario.
