Rushed eating starters in Indian, carefully seasoned (6)
I believe the answer is:
spiced
'seasoned' is the definition.
(spicing is a kind of seasoning)
'rushed eating starters in indian carefully' is the wordplay.
'rushed' becomes 'sped' ('speed' can be a synonym of 'rush').
'eating' indicates putting letters inside.
'starters in' says to take the initial letters (the letters which start the words).
The first letters of 'indian carefully' is 'ic'.
'sped' placed around 'ic' is 'SPICED'.
(Other definitions for spiced that I've seen before include "given a smack" , "Given more flavour" , "Flavoured with such as nutmeg" , "Flavoured with aromatic substances" , "was over-scrupulous" .)
