Operating Instructions
The SEVERIN JG 3518 Yogurt Maker maintains a constant temperature for optimal fermentation, ensuring consistent results.
Preparing Yogurt
- Prepare your mixture: Combine milk (dairy or plant-based like soy or coconut milk for vegan yogurt) with a starter culture (e.g., a few tablespoons of plain yogurt with live cultures, or a commercial yogurt starter). For best results, some users pre-warm milk to 37-38°C before adding the starter.
- Fill the jars: Pour the mixture into the clean glass jars. Do not overfill.
- Place jars in the unit: Arrange the filled, open jars inside the yogurt maker.
- Cover the unit: Place the transparent lid on the main unit. The integrated time display on the lid can be manually set to remind you of the fermentation start time or desired duration.
- Start fermentation: Plug the appliance into a suitable power outlet. Press the illuminated on/off button to start the fermentation process. The indicator light will illuminate.
- Fermentation time: The fermentation process typically takes 5 to 9 hours, depending on the milk temperature and desired consistency.
- For cold milk: Approximately 8-9 hours.
- For pre-warmed milk: Approximately 5-6 hours.
- For firmer yogurt, you may extend the fermentation time up to 14 hours, as suggested by some users.
- Stop fermentation: Once the desired consistency is achieved, press the on/off button to switch off the appliance. The appliance features an automatic shut-off function, but manual intervention is also possible.
- Cooling and storage: Remove the jars from the yogurt maker, screw on their lids, and refrigerate immediately for at least 2-3 hours to stop the fermentation process and firm up the yogurt.
