*Obviously most of you will not have Julie's spice mixture. I'm sorry. But don't let this scare you away from the recipe. I don't know exactly what she puts in her spice rub, but I recommend adding in garlic powder, onion powder, sea salt, cayenne pepper, paprika, and a bit of red pepper flakes. You'll get a good spice that will be offset by the citrus and mango flavors combined.
