That's why I put the T in brackets, the clue says 'somewhat hot' meaning 'in some degree' = not all of it, hence ho(t) minus the 't' + can HOCAN = Nacho (anag)
If that is Nacho witzend, then (from the clue ref) 55 is something that goes with Nachos, which would be some mexican food, can't think of anything at moment with a colour in it
