Claims keen cooks make traditional Easter fare (6,4)
I believe the answer is:
simnel cake
'traditional easter fare' is the definition.
(I've seen this before)
'claims keen cooks' is the wordplay.
'cooks' is an anagram indicator.
'claims'+'keen'='claimskeen'
'claimskeen' is an anagram of 'SIMNEL CAKE'.
'make' acts as a link.
(Other definitions for simnel cake that I've seen before include "Easter confection" , "Traditional Easter fare" .)
