This bean crushed in liqueur (8)
I believe the answer is:
absinthe
'liqueur' is the definition.
(absinthe is a kind of liqueur)
'this bean crushed' is the wordplay.
'crushed' indicates an anagram.
'this'+'bean'='thisbean'
'thisbean' anagrammed gives 'ABSINTHE'.
'in' is the link.
(Other definitions for absinthe that I've seen before include "Potent aniseed-flavoured drink" , "Aniseed flavoured liqueur" , "Strong green alcoholic drink" , "Green aniseed liqueur" , "intoxicant" .)
