Preheat a grill over medium-high heat. Lightly oil the grill grates. Grill the red chiles and habaneros, turning occasionally, until charred all around. Cut stems off and let cool. In the bowl of a food processor, combine the charred chiles with the vinegar, cayenne, salt, sugar, xanthan gum and 1 cup water. Blend well. Serve with anything, but beware of spiciness!
