Schwenker is a special type of German barbecue that involves grilling meat on a swinging iron contraption over an open fire. The meat is placed on a long metal arm that is attached to a hinge, allowing it to rotate and sway back and forth. As the meat cooks, the schwenker must be carefully monitored and turned regularly to ensure that it cooks evenly and doesn't burn. This type of cooking requires patience and skill, but the end result is a delicious and unique flavor that can't be achieved with traditional barbecuing methods. Simply put, schwenker is like playing on a swing set while cooking meat.
