Emergency worker concocted a cream dip (9)
I believe the answer is:
paramedic
'emergency worker' is the definition.
(I've seen this before)
'concocted a cream dip' is the wordplay.
'concocted' is an anagram indicator.
'a'+'cream'+'dip'='acreamdip'
'acreamdip' is an anagram of 'PARAMEDIC'.
(Other definitions for paramedic that I've seen before include "Epic drama (anag.)" , "Emergency first-aider" , "Professional first-aider" , "Assistant in ambulance maybe" , "Member of ambulance crew" .)
