A little application and skill used to make dessert (5,4)
I believe the answer is:
apple tart
'dessert' is the definition.
(I've seen this before)
'a little application and skill' is the wordplay.
'a little application' becomes 'applet'.
'and' is a charade indicator (letters next to each other).
'skill' becomes 'art' (I've seen this before).
'applet'+'art'='APPLE-TART'
'used to make' is the link.
(Other definitions for apple tart that I've seen before include "Pastry" , "Sweet" , "Dessert" .)
