I AM LOOKING FOR SOME MIXES THAT CAN BE USED IN ELECTRIC ICE CREAM MACHINES ( the ones for the home that make 1 1/2 qts.)I like the taste of Braum's Softserve Yogurt and am looking for something like it. I would like to know if anyone has tried some of these dry mixes & if they were satasfied with the taste;

Or if there is another brand that you know tastes good and that will sell to the public.
Thank You
