The principle of yoghurt fermentation is actually very simple. It is to add a fermenting agent to pure milk and give it a constant temperature. After a long period of fermentation, the yogurt machine is just an electric heating incubator. Understand this truth, use a rice cooker to maintain a certain temperature, you can still make a taste, taste, first-class yoghurt.
A container of suitable size, first boiled with boiling water;
Pour milk and yogurt baking powder;
Stir well and do not see small particles of the starter;
Put a shelf in the inner pot of the rice cooker, add the rolled water, and the water volume is consistent with the height of the shelf;
Put the milk with yogurt powder;
Cover the lid (do not seal, cover it), put it into the inner pot of the rice cooker, and fasten the lid -rr The first stage: leave it alone, ferment the yogurt with the temperature of hot water, time: 3 hours;rr The second stage: power on, set the insulation function of the rice cooker, time: 2 hours;rr The third stage: cut off the power, leave it alone, time 5 hours.
1. Adjust the heating time and fermentation time according to the state of the rice cooker. 2, the use of shelves can prevent direct contact between milk and hot water, too high temperature will burn the fermentation bacteria; similarly, the heating time can not be too long; if there is time, you can warm up for a short time. 3. If there is no problem with baking powder and milk, it will not fail. 4, on the issue of adding no sugar, you can add; it is best to do yogurt, add when you eat.
