Material to make decorative display for candles? (5,5)
I believe the answer is:
icing sugar
'material' is the definition.
Both the definition and answer are singular nouns.
Perhaps there's an association between them I don't understand?
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for icing sugar that I've seen before include "Cake covering" , "Sweet stuff used for cake topping" , "Sweet powder used on cakes etc" .)
