Strait of Gibraltar port (7)
I believe the answer is:
'strait of gibraltar port' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for tangier that I've seen before include "More piquant; Strait of Gib. port" , "Rather spicy" , "North African port" , "Moroccan seaport made of granite" , "Seaport of Morocco, opposite Gibraltar" .)
