Rating 850,000 to 1,000,000 Scovile Heat Units, ghost chiles are HOT. For reference, jalapeños rate around 5,000 SHUs. Add this powder to anything you want for a big kick of heat from chilis and barbecue sauces to dry rubs and marinades. Use sparingly, or if you're brave, use as much as you like. Just keep a glass of milk nearby.
