Bringing back rice (about a pound) and a cake (6)
I believe the answer is:
eclair
'cake' is the definition.
(I've seen this before)
'bringing back rice about a pound and a' is the wordplay.
'bringing back' is a reversal indicator (I've seen 'brought back' mean this).
'about' is an insertion indicator.
'a pound' becomes 'L' (abbreviation e.g. Lsd - pounds, shillings, pence).
'and' means one lot of letters go next to another.
'l' put after 'a' is 'al'.
'rice' going around 'al' is 'rialce'.
'rialce' back-to-front is 'ECLAIR'.
(Other definitions for eclair that I've seen before include "Food" , "Dainty" , "Long chocolate cake for Claire" , "Cake, "long in shape but short in duration"" , "Finger-shaped cream-filled cake of choux pastry" .)
