Delicious Stone
From MHWiki
These tasty small rocks are collected by members of the Derr tribe within the dunes of Tribal Isle and are used to create Crunchy cheese. 30 of these rocks are combined with 20 servings of coconut milk, 10 curds and whey and 30 dashes of salt to make 15 pieces of tooth-chipping cheese.
Dropped by Mintaka, Renegade, and Spellbinder in Derr Dunes.
