The rough part of making your favorite meals in New World are the limited and hard to find ingredients. Rice is just ONE hard to find resource!
Currently Rice can be found in Monarch’s Bluffs, Restless Shore, and Shattered Mountain. There’s a catch though: You still have to grind Provision crates which have a chance to spawn your needed ingredient.
Provision crates will respawn around the 45 minute mark after you have opened them.
