Temperature on a fine cheese material (7)
I believe the answer is:
taffeta
'material' is the definition.
(taffeta is a kind of material)
'temperature on a fine cheese' is the wordplay.
'temperature' becomes 't' (abbreviation).
'on' says to put letters next to each other.
'a fine' becomes 'af' (I've seen this in other clues).
'cheese' becomes 'feta' (I've seen this before).
't'+'af'+'feta'='TAFFETA'
(Other definitions for taffeta that I've seen before include "Shiny silk fabric" , "Thin crisp lustrous silk" , "Lustrous silky fabric" , "Smooth, stiff fabric" , "Stiff, silky fabric" .)
