Hey supersweet (and anyone else),
I buy Three Twins ‘Sea Salted Caramel’ organic ice cream. It is DE-LISH! I don’t know in which states it is sold, but I have access to it at my Whole Foods in the greater Seattle area.

I think making your own is ideal, but the cost may come out to be more-or-less the same as just buying it. But, hey, if you got it to work for you, keep it up!
