Cooks irk a yeti with a Japanese dish (8)
I believe the answer is:
teriyaki
'japanese dish' is the definition.
(I've seen this before)
'cooks irk a yeti' is the wordplay.
'cooks' is an anagram indicator.
'irk'+'a'+'yeti'='irkayeti'
'irkayeti' is an anagram of 'TERIYAKI'.
'with a' acts as a link.
(Other definitions for teriyaki that I've seen before include "Oriental food" , "Basted and broiled" , "Japanese dish of cooked meat or seafood, marinated in soy sauce" , "Japanese dish of beef, chicken or seafood, marinated in soy sauce" , "Japanese cooking using sweet soy sauce" .)
