Stews over carrying eastern bonbons (6)
I believe the answer is:
sweets
'bonbons' is the definition.
(I've seen this in another clue)
'stews over carrying eastern' is the wordplay.
'over' shows that the letters should be reversed in order.
'carrying' means one lot of letters goes inside another.
'eastern' becomes 'e'.
'stews' in reverse letter order is 'swets'.
'swets' enclosing 'e' is 'SWEETS'.
(Other definitions for sweets that I've seen before include "Desserts" , "Pieces of confectionery" , "courses" , "Confectionery, candies" , "Prohibited food for dieters" .)
