So delicious!!! Our family loved it! We used our cuisineart ice cream machine to slush the cream soda and it worked perfect!

I did this, however, didn't have kosher salt, so just used table salt. Even after 30 mins of shaking and putting it into the freezer, it's still not slush-ied. Does the type of salt matter? Or am I just doing something wrong?
