Boy tucked into it, an Indian savoury (6)
I believe the answer is:
samosa
'an indian savoury' is the definition.
(I've seen this before)
'boy tucked into it' is the wordplay.
'boy' becomes 'amos' (**).
'tucked into' is an insertion indicator.
'it' becomes 'sa' (old-fashioned abbreviation for sex appeal).
'amos' placed within 'sa' is 'SAMOSA'.
(Other definitions for samosa that I've seen before include "Small Indian turnover, fried and served hot" , "Indian dish" , "A bit of food" , "Savoury Indian snack" , "Triangular Indian turnover" .)
