I am living in Australia and having a hard time finding a good substitute for Nestle semisweet chocolate chips. What should I look for in a good quality semi-sweet chocolate chip in Australia and where can I find them? 
My mother in law has had the same troubles as she uses the nestle semi sweet morsels for chocolate crack cookies. The cookies just don't crack the same with other chocolate chips. She tells me it is due to the quality of the cocoa butter. She has experimented and found a half-half mix of cadbury dark choc chips and milk chocolate chips does the job.
