Confectioner's outlet, the best place for making contact? (5,4)
I believe the answer is:
sweet spot
(Other definitions for sweet spot that I've seen before include "Best point of racket or bat when hitting the ball" , "Best place to make contact" , "Most effective section of racket" , "providing an optimum combination of qualities" , "Area on club, racket or bat that makes best contact with the ball" .)
