Cheese melted near Spam (8)
I believe the answer is:
parmesan
'cheese' is the definition.
(Parmesan is an example)
'melted near spam' is the wordplay.
'melted' indicates an anagram.
'near'+'spam'='nearspam'
'nearspam' anagrammed gives 'PARMESAN'.
(Other definitions for parmesan that I've seen before include "Italian cheese for spearman" , "Hard dry Italian cheese" , "Cheese for grating" , "Pam earns this cheese" , "Dry sharp-flavoured Italian cheese" .)
