Relish tight spot (6)
I believe the answer is:
pickle
I believe this is a double definition.
'relish' is the first definition.
(pickle is a kind of relish)
'tight spot' is the second definition.
(I've seen this in another clue)
(Other definitions for pickle that I've seen before include "Jam - vegetables preserved in vinegar or brine" , "Preserved vegetable of informal plight" , "Marinate" , "Awkward situation" , "Relish; predicament" .)
