Plainer mixture of nuts and sugar (7)
I believe the answer is:
praline
'nuts and sugar' is the definition.
I can't judge whether this defines the answer.
'plainer mixture' is the wordplay.
'mixture' indicates anagramming the letters.
'plainer' anagrammed gives 'PRALINE'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for praline that I've seen before include "Sweet stuff" , "Sweet, nutty chocolate filling" , "Chocolate filling of nuts and sugar" , "Smooth nut filling" , "confectionery" .)
