Admire a fantastic cake? (7)
I believe the answer is:
madeira
'cake?' is the definition.
(I've seen this before)
'admire a fantastic' is the wordplay.
'fantastic' indicates an anagram.
'admire'+'a'='admirea'
'admirea' with letters rearranged gives 'MADEIRA'.
(Other definitions for madeira that I've seen before include "Atlantic island, famed for its sweet wine" , "Islands in the Stream?" , "cake producer" , "A fortified wine, a rich sponge" , "Rich, fortified white wine" .)
