Art displayed in a bake-off (7)
I believe the answer is:
ikebana
'art' is the definition.
(Japanese art of flower arranging)
'in a bake-off' is the wordplay.
'off' indicates an anagram.
'in'+'a'+'bake'='inabake'
'inabake' anagrammed gives 'IKEBANA'.
'displayed' is the link.
This may not be correct. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for ikebana that I've seen before include "Japanese art of flower arranging" , "Jap. flower arranging" , "exhibiting array of bloomers" , "formal display" , "Japanese flower-arranging art" .)
