What is a good ice cream maker?
One that is under $100 and doesn't use salt.
The Cuisinart ICE-21 seems to be a good one.
The Cuisinart ICE-21 is the Cook's Illustrated Best Buy. It is the number two ice cream machine they rated.
The number one ice cream machine they rated is the Whynter IC-2L SNO 2-Quart Ice Cream Maker which costs about $300.
I've had a Donvier and another similar type. They worked well. Like the Cuisinart you have to put that mixing container in your freezer and have it upright and level.
2 years ago I bit the bullet and bought the Cuisinart model that has its own compressor. $299.00. I am not sorry I spent the money. I frequently make ice cream, sorbets etc. Last weekend I wanted a Watermelon Martini, recipe is in the Hot and Hot Fish Club cookbook. They are dangerously delicious. It was after 4 PM when I had chopped up the melon, pureed it in my blender and strained it. I took that juice and put it in the ice cream freezer and in about 30 minutes I had semi-frozen watermelon juice that was perfect. I have used it to chill soups quickly too.
The downside of this machine is that if you are seriously lacking in space for kitchen equipment, this machine must be stored up-right. Luckily I have a front loading washing machine so the ice cream freezer lives in my laundry room on top of the washer. If it gets turned on its side for some reason, like getting it home from Bed Bath & Beyond it will need to sit upright for 24 hours before using. Mine is always ready to use, it never gets moved, and it does a great job.
