Ketkrókur (Meat-Hook) This Yule lad, the twelfth, uses a metal hook to grab meat, especially lamb hanging to be smoked. He then eats the meat, causing him to grow big and strong. Less and less meat is being hung these days, so he could use the hook to open plastic packets I suppose. Vegetarianism doesn’t mean anything to this lad. Ketkrókur arrives on December 23 and leaves on January 5.
