Citrus gram to be pulped (8)
I believe the answer is:
bergamot
'citrus' is the definition.
(bergamot is a kind of citrus)
'gram to be pulped' is the wordplay.
'pulped' indicates an anagram (the original order of letters is crushed or pulped).
'gram'+'to'+'be'='gramtobe'
'gramtobe' with letters rearranged gives 'BERGAMOT'.
(Other definitions for bergamot that I've seen before include "Flavouring in Earl Grey tea" , "perfume" , "Variety of pear" , "Fine pear" , "essential oil" .)
