The paste form of the sauce comes from Da' Bomb Hot Sauce.
Ghost Pepper Sauce is available at Panchero's Mexican Grill through Monday, October 21. The sauce is served on the side so the level of spiciness doesn't overwhelm those eating it.
Panchero's has two locations in Arizona. One is located in Tempe off Loop 202 and Scottsdale Road, and the other is in Chandler on the southwest corner of Chandler Boulevard and Dobson Road.
