Worry about contents of aloo gobi portion? (6)
I believe the answer is:
floret
'gobi portion?' is the definition.
(piece of cauliflower ie gobi)
'worry about contents of aloo' is the wordplay.
'worry' becomes 'fret' (to fret about something is to worry).
'about' means one lot of letters goes inside another.
'contents of' indicates the central letters (the letters on the inside of the word).
The middle letters of 'aloo' are 'lo'.
'fret' going around 'lo' is 'FLORET'.
(Other definitions for floret that I've seen before include "Part of cauli head" , "Small flower" , "Part of a cauliflower or broccoli head" , "Broccoli stem" , "Piece of broccoli" .)
