Relish tricky situation (6)
I believe the answer is:
pickle
I believe this clue is a double definition.
'relish' is the first definition.
(I know that pickle is a type of relish)
'tricky situation' is the second definition.
(I've seen this before)
(Other definitions for pickle that I've seen before include "A preserve or an informal predicament" , "Mischief-maker" , "Condiment - tricky situation - troublesome child" , "Preserve in brine or vinegar" , "Lather - relish" .)
