5.1 Making Yogurt

Figure 4: Step-by-step visual guide for yogurt preparation.
- Disinfect: Disinfect the stainless steel inner liner and ceramic cups (if using) with high-temperature hot water. Ensure they are clean and dry.
- Prepare Mixture: Pour 500-1000ml of pure milk into the stainless steel inner liner. Add an appropriate amount of yogurt starter (mushroom powder) and stir well. If using ceramic cups, divide the mixture among them.
- Start Fermentation: Place the inner container(s) into the yogurt maker. Cover with the top lid and plug in the power cord. Press the 'Function' button to select the 'Yogurt' mode. The default fermentation time is typically 8-10 hours. Adjust time with 'Time+' or 'Time-' buttons if needed. Press 'Confirm' to start.
- Enjoy: Once fermentation is complete, the machine will stop. Remove the yogurt and refrigerate for a few hours before serving. You can add an appropriate amount of fruit or other toppings for a better taste.
5.2 Making Rice Wine
The Bear SNJ-B10K1 can also make rice wine. Follow the specific recipe for rice wine preparation, then place the mixture in the stainless steel inner liner. Select the 'Rice Wine' function. The recommended fermentation time is 32-48 hours. Adjust as needed based on desired taste and ambient temperature.

5.3 Making Natto
