- "A result of Kilton's research into monsters, this suspicious spice can be used to punch up dishes while cooking. Apparently it can be used to make a number of monstrous meals."
- — In-game description
The Monster Extract is an item from The Legend of Zelda: Breath of the Wild. It is a special spice ingredient. Link can purchase it at the Fang and Bone for 9 Mon after having met Kilton at Skull Lake at night. Link can also obtain it as a reward by rescuing from monsters the Hylian traveler Chabi searching for the Kilton's shop.
As it is a spice made from Kilton's monster research, it is classified as a "Monster Part" ingredient, along with Monster, Guardian, and Dragon parts. Link can thus sell it to Kilton for 2 Mon. However, it cannot be used to as a Monster Part to create Elixirs as cooking it with any critter results in Dubious Food. Link can cook with it to prepare "Monster" based dishes, and the amount of hearts restored is randomly determined when it is cooked.
