Disclosed is a wienie roaster with prongs that may be folded back. The prongs are pivotly received by a head, and the head is attached at the end of a roaster stalk. The prong has a continuous curve as it enters the head which produces friction to hold the prongs at an adjustable angle away from or towards the roaster stalk. The bore in the head may have beveled, oval-shaped openings, so that the curved base of the prong notches into place in extended and folded back positions. The roaster may also have a tension shoe for applying and distributing pressure on the prongs and a notch in the prongs for receiving the tension shoe. A hole in the top of the head allows lubricant, such as oil or fat from cooking food, to enter the head and lubricate the base of the prong and the tension shoe. The lubrication hole may also be threaded to receive a set screw, which can provide additional pressure to hold the prong in place. In an another alternative embodiment, the base of the prong has notches to receive the tip of the roaster stalk. In this embodiment, the prong is held in its extended and folded back positions when the tip of the stalk enters the notches in the base of the prong. The end of the stalk may be threaded to receive the head, so that the head can be screwed out a little to allow the base of the prong to clear the tip of the stalk, thereby permitting the prong to be swivelled to its extended or folded position. Alternatively, a spring and ball at the end of the stalk can exert enough pressure to hold the ball in the notches of the prong base to hold the prong in position, yet still allow the prong to be swivelled.
