I'm looking for some information on what kind of hot sauce is put on fried chicken in chicken shacks like Harold's of Chicago or Prince's Hot Chicken of Nashville. Is it just bottled hot sauce like Crystal or Tabasco or is it a butter/hot sauce/vinegar mix like on chicken wings?
I've never been to either of these places but I've seen Prince's on Comedy Central's Insomniac and Harold's on another web site and the chicken looks great.
Any info would be appreciated. Thanks!
