Sweet almond paste (8)
I believe the answer is:
marzipan
'sweet almond paste' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for marzipan that I've seen before include "Sweet paste of ground almonds" , "coat often iced over?" , "Sweet almond paste" , "Cake icing made of ground almonds and sugar" , "almond concoction" .)
