The Elhrimnir Kettle was used by the cook Andhrimnit ("Sooty face") to cook the boar, Saehrimnir, which was used to feed the hungry Einherjar in Valhalla every night. Odin himself abstained from eating.

"For meat, they all feast on the boar Saehrimnir for, although the boar is boiled every morning, he becomes whole again every night."

-- Gylfaginning 39
