I appreciate that strong cheese, crisp and silky stuff (7)
I believe the answer is:
taffeta
'silky stuff' is the definition.
(I've seen this before)
'i appreciate that strong cheese' is the wordplay.
'i appreciate that' becomes 'ta' (informal way of saying thank you).
'strong' becomes 'f' (musical symbol for 'forte', 'strong' in Italian).
'cheese' becomes 'feta' (type of cheese).
'ta'+'f'+'feta'='TAFFETA'
'crisp and' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for taffeta that I've seen before include "Stiff, silky fabric" , "Fine crisp silk fabric" , "Smooth, stiff fabric" , "Sheeny fabric" , "cloth" .)
