Country having unlimited sugar and bananas (6)
I believe the answer is:
uganda
'country' is the definition.
(Uganda is an example)
'unlimited sugar and bananas' is the wordplay.
'unlimited' says to take the centre (discard the edges or 'limits' of the word).
'bananas' is an anagram indicator (informal term for mad).
The middle of 'sugar' is 'uga'.
'and' anagrammed gives 'nda'.
'uga'+'nda'='UGANDA'
'having' acts as a link.
(Other definitions for uganda that I've seen before include "It was Idi Amin's country" , "East African republic" , "Country W. of Kenya" , "E. African country" , "part of Africa" .)
