Dealing with Turkey by scoffing (8)
I believe the answer is:
treating
'dealing with' is the definition.
('treat' can be a synonym of 'deal with')
'turkey by scoffing' is the wordplay.
'turkey' becomes 'tr' (abbreviation eg in internet addresses).
'by' is a charade indicator (letters next to each other).
'scoffing' becomes 'eating' (scoff can mean to eat).
'tr'+'eating'='TREATING'
(Other definitions for treating that I've seen before include "Giving medical attention or paying for someone" , "Dealing with" , "Standing a drink" , "Giving medical care to" , "Negotiating (with); handling" .)
