Claims keen cooks make traditional Easter fare (6,4)
I believe the answer is:
Here is my best explanation:
'traditional easter fare' is the definition.
(I've seen this before)
'claims keen cooks' is the subsidiary indication.
'cooks' indicates an anagram.
'claimskeen' anagrammed gives 'simnelcake'.
'make' is the link.
(Other definitions for simnel cake that I've seen before include "Easter confection" and "Traditional Easter fare".)
