Some French group eating first bit of rice pudding? (7)
I believe the answer is:
dessert
'pudding?' is the definition.
(pudding is a kind of dessert)
'some french group eating first bit of rice' is the wordplay.
'some french' becomes 'des'.
'group' becomes 'set' (set is a kind of group).
'eating' is an insertion indicator.
'first bit of' says to take the initial letters.
The initial letter of 'rice' is 'r'.
'set' going around 'r' is 'sert'.
'des'+'sert'='DESSERT'
(Other definitions for dessert that I've seen before include "Charlotte maybe" , "Fruit and nuts, perhaps" , "End of meal" , "Fool possibly" , "Sweet, afters" .)
