Sugar made with rare ingredients (8)
I believe the answer is:
demerara
'sugar' is the definition.
(I've seen this before)
'made with rare ingredients' is the wordplay.
'with' says to put letters next to each other.
'ingredients' is an anagram indicator.
'made' put after 'rare' is 'raremade'.
'raremade' with letters rearranged gives 'DEMERARA'.
(Other definitions for demerara that I've seen before include "Rum" , "Light brown cane sugar" , "Sweet thing" , "That's sweet!" , "Source of sweetness" .)
