4. Operating Instructions
Follow these steps to prepare delicious homemade ice cream, sorbets, or frozen yogurts.
- Prepare Ingredients: Prepare your desired ice cream, sorbet, or frozen yogurt mixture. Ensure the mixture is chilled in the refrigerator before adding it to the ice cream maker. The maximum capacity for preparation is 550 grams (approximately 550 milliliters) of ice cream per process.
- Start the Food Processor: With the ice cream maker attachment assembled and the thermal container frozen, turn on your OptiMUM food processor to a low speed setting. The agitator should begin to rotate.
- Add Mixture: Slowly pour your chilled mixture through the opening in the transparent lid while the agitator is running.
- Churn: Allow the mixture to churn for approximately 20-30 minutes, or until it reaches your desired consistency. The churning time may vary depending on the recipe and the initial temperature of your mixture.
- Serve or Store: Once the desired consistency is achieved, turn off the food processor. Use the included spatula to remove the ice cream from the thermal container. For a firmer consistency, transfer the ice cream to an airtight container and freeze for an additional 30-60 minutes.
Tips for Best Results:
- Ensure the thermal container is thoroughly frozen.
- Chill your ice cream mixture completely before churning.
- Experiment with various ingredients, including low-calorie, low-fat, or lactose-free options, to suit your dietary preferences.
