The sausage grilling is part of the NovtumberFest located in the northern part of the crater. It is led by Jakob. Grilling sausagess grants the player Cooking experience.
There are two grills that can be used to cook sausages without any resources. Each interaction with the grill yields experience twice, and after the second one a novtumberfest sausage is obtained, provided that there is space in inventory. Experience is gained in 9-second intervals. At level 99 Cooking, 350.4 experience is gained at a time.
There is a confirmation prompt about gaining experience before starting this activity that can be toggled off permanently.
