Come back with some mediocre curry (5)
I believe the answer is:
recur
'come back' is the definition.
(recurring is a kind of coming back)
'with some mediocre curry' is the wordplay.
'with' says the answer is hidden in the clue.
'RECUR' can be found hidden inside 'some mediocre curry'.
(Other definitions for recur that I've seen before include "Repeat" , "Come round again" , "Persist" , "Perseverate" , "Happen again (5)" .)
