Extra ice mixed with first of tequilas for free (9)
I believe the answer is:
extricate
'free' is the definition.
(extricating is a kind of freeing)
'extra ice mixed with first of tequilas' is the wordplay.
'mixed with' indicates anagramming the letters.
'first of' says to take the initial letters.
The initial letter of 'tequilas' is 't'.
'extra'+'ice'='extraice'
'extraice' with its letters mixed up with 't' makes 'EXTRICATE'.
'for' is the link.
(Other definitions for extricate that I've seen before include "Free (something) from difficulty" , "get out from difficult situation" , "Free from entanglements" , "Free from entanglement" , "wriggle free" .)
