Xiaoxi mother can't afford the yogurt machine, but the kitchen is small and there is no place to put these things. Plus Xiaoxi mother is professional, can use the rice cooker to make the yogurt well, kill all kinds of yogurt machine on the market, decided to share the method for everyone.
Heat the milk to 40 degrees, touch the temperature to the hand, a little higher than the body temperature. If you use milk powder, you can use it directly with warm water.
Mix the milk, sugar and the bottle, then spoon a spoonful of yogurt. Yogurt really doesn't have much, just a small spoon. Because of the fermentation process, the bacteria will grow in logarithm, a spoonful of two, two become four, four to eight, so do not worry about the amount of yogurt, the people are not bad for this spoon half a spoon. If the money in the bank can grow like this, it would be fine.
Lactic acid bacteria are anaerobic bacteria, and the bottle must be sealed and covered. Because the bottle I used does not have a cover, I can add a plastic wrap. It is really recommended to have a sealed lid cup that is directly sealed for easier and safer.
The key step! The rice cooker first heats the water to 40-50 degrees. It is probably a hot but comfortable temperature. Lactic acid bacteria are also biological, and they feel comfortable at temperatures that they feel comfortable with. After putting the milk in it, you can cover it and let them soak in the hot spring. When you are soaking, remember not to heat or keep warm. It is enough to keep warm by the waste heat of the rice cooker.
Bubbles bubble ~ bubble bubble ~ bubble bubble ~ milk slowly solidified, into a fragrant and smooth yogurt. In terms of time, according to experience, it may be ok in two or three hours in the summer. Hemp said while eating, these are the bacteria who eat the yogurt and pull out the thick si.
Remember, the rice cooker has good heat preservation. When it is kept warm, it should be powered off by residual heat to prevent the bacteria from inactivating due to overheating. A good yoghurt can be used as a primer to make the next batch, but the number and quality of passages will vary depending on the strain. Recommend one, Guangzhou's friends can try Huanong yogurt, taste and flavor are very good.
