The Hard-Boiled Egg is an item from The Legend of Zelda: Breath of the Wild. It is a curative item that restores Link's health with one and half Heart Containers. One is found at Hyrule Castle and Link can boil a Bird Egg by dropping it in a Hot Spring.
Hot Springs can be found primarily in the Eldin province, though Link can find secret hot springs in the Hebra Mountains region. A small Hot Spring can also be found northeast of Breman Peak and southwest of Mount Rozudo in the West Necluda region.
