|Puree your berries!|
|Just say no to seeds!|
Any fruit, whether macerated or cooked, should be pureed to be smooth. When it comes to cranberries, you will want to run them through a food mill to remove the skins. Trust me, learned that one the hard way too. Then, if you don't like seeds in your ice cream, run it through a sieve. A laborious process, I know, but totally worth it if the only thing you want to be crunching in your ice cream is chocolate chips, and not seeds.
