Right pub in centre offering this item in crumble? (7)
I believe the answer is:
rhubarb
'this item in crumble?' is the definition.
(rhubarb crumble is a type of dessert)
'right pub in centre' is the wordplay.
'right' becomes 'r' (common abbreviation).
'pub' becomes 'bar' (I've seen this before).
'in' is an insertion indicator.
'centre' becomes 'hub' (hub is a kind of centre).
'bar' placed within 'hub' is 'hubarb'.
'r'+'hubarb'='RHUBARB'
'offering' is the link.
(Other definitions for rhubarb that I've seen before include "Plant grown for its stalks" , "Edible stem" , "murmurings in the theatre" , "Hand covering" , "In America, heated dispute" .)
