Ingredients in The Elder Scrolls Online are used in cooking to create food and beverages using the Provisioning skill set. They can be found throughout the game, but much more commonly in barrels, crates, and sacks. They can also be received from Hirelings or bought from Grocers. Those looking to purchase ingredients in bulk are suggested to look at buying from Guild Traders.
In Update 6 Provisioning was revamped and most of the ingredients were either removed or converted into new ones. Before the update ingredients were unique to the alliances' regions and leveled.
