Cut the beef into very thin strips (partially frozen helps a lot), and marinade overnight. Pat dry and dehydrate! This is not OUTRAGEOUSLY hot, but certainly enough to make it completely avoided by my non-CH friends (pathetic masses....), and really big hit on a white-water rafting trip with a boat-load of thrill-seekers. I really liked the pineapple, but you could probably use just about any acidic fruit juice. Posted to CHILE-HEADS DIGEST V4 #177 by Ed Cutrell <ecutrell@darkwing.uoregon.edu> on Oct 29, 1997
