Starter of samosa with considerable taste (6)
I believe the answer is:
sample
'taste' is the definition.
('sample' can be a synonym of 'taste')
'starter of samosa with considerable' is the wordplay.
'starter of' indicates taking the first letters.
'with' is a charade indicator (letters next to each other).
'considerable' becomes 'ample'.
The first letter of 'samosa' is 's'.
's'+'ample'='SAMPLE'
(Other definitions for sample that I've seen before include "Take" , "Small part representative of the whole" , "Test piece" , "Specimen, try out" , "Small part intended to represent the whole" .)
