Made this with the double chocolate base. Made a cherry puree, chopped up some chips and cherry pieces and layered and swirled it in. Screwed up my first batch of Vanilla by forgetting to add the second cup of milk and my kids were rushing me so I do not think the machine insert was really cold enough so that batch never really thickened and it is icy.I was not sure when to stop the churning. I had this going for 45 min.
