Urged natural gas reform, maybe a sweetener needed? (10,5)
I believe the answer is:
granulated sugar
'a sweetener needed?' is the definition.
(I've seen this before)
'urged natural gas reform' is the wordplay.
'reform' is an anagram indicator (letters in a new form).
'urged'+'natural'+'gas'='urgednaturalgas'
'urgednaturalgas' with letters rearranged gives 'GRANULATED SUGAR'.
'maybe' is the link.
(Other definitions for granulated sugar that I've seen before include "White sweetener" , "sweetener needed" .)
