I have a cuisinart and i freeze the base for 24 hours, you want it very frozen ! i make any ice cream base pour it in and turn it on about 30 min or so the ice cream is somewhat soft delicious and when i freeze it well it gets hard lol and does not stay nice like the store icecream i wish i could find a recipe that would stay nice and easy to scoop. i have to take mine out and let it sit a spell.
