Frequently Asked Questions of how to use cuisinart ice cream maker ice-21
How long should I freeze the bowl before using the ICE-21?
Freeze the bowl for 12–24 hours in the coldest part of your freezer. A fully frozen bowl is essential for good results.
Can I pour a warm mixture into the ICE-21?
No. Warm mix slows freezing and makes ice crystals. Always chill the base in the fridge first.
How much ice cream does the ICE-21 make per batch?
The ICE-21 handles about 1.5 quarts of mix but yields slightly less finished ice cream due to air volume. Do not overfill to avoid spillage.
Do I need eggs for a rich ice cream in the ICE-21?
Eggs help create a custard base with a rich mouthfeel, but you can use eggless recipes with cream and stabilizers for good results. Adjust sugar and fat for texture.
How do I add mix-ins like nuts or chocolate chips?
Add chunky mix-ins during the last 2–3 minutes of churning so they distribute evenly. Adding them too early causes sinking or uneven texture.
