How many hours does it take to make yogurt in summer

In the summer, if people have free time at home, they like to make some delicious food by themselves, such as learning to make yogurt by themselves. In fact, the method of making simple yogurt is not that complicated, and it does not take too long, but after it is made, it needs to be refrigerated in the refrigerator. It needs to be refrigerated for about eight hours, so that it can taste better.

Preparation method: Boil the milk and pour it into a clean, oil-free container. When the milk is warm, pour in a small box of plain yogurt and stir well. Cover the container and leave it for about eight hours in summer. After the yogurt is made, put it in the refrigerator. It will taste better and the yogurt will not become more sour.

Please be reminded that:

1. The amount of milk should be enough for you to drink for two days, about 500 ml. If you make too much and leave it for too long, the yogurt will become too sour and will not taste good.

2. It is best to choose the refrigerator and microwave storage box sold on the market. This type of container has a good sealing effect and the yogurt is not easy to deteriorate.

3. Don’t add sugar when making yogurt. It will taste better when you eat it.

There is a yellow layer on the yogurt, which is the milk skin.

In summer, the room temperature should be above 30℃. It’s just that the coagulation time is longer, and the higher the room temperature, the shorter the coagulation time. The method is to wash the wide-mouthed glass bottles or porcelain bottles (canning bottles cannot be used because their mouths are too large and they are easily contaminated by bacteria), fill them with milk, cover the bottle mouths with a clean double-layer plastic film, and tie them with string. The string should be tied loosely because a lot of steam will be generated in the bottle during the heating process. If it is tied too tightly, the film will burst and contamination will easily occur. Put the glass bottle with milk into the pot and boil it for 30 minutes. The water should cover the surface of the milk. Do not cover the pot. Then take it out and cool it until it is not hot to touch the back of your hand. Then pour in 2% - 4% of fresh pure yogurt sold in the market. After adding the purchased yogurt, tie the plastic film tightly immediately to ensure an oxygen-free environment in the bottle. After 10 hours at room temperature, the fresh milk will coagulate like tofu pudding and yogurt is ready. Place the yogurt bottle in a refrigerator at 0-5℃ and refrigerate for 2-4 hours. It is ready to eat. White sugar can be added during sterilization or when eating. The amount depends on personal taste and it may not be added. You can make a separate small bottle when making it. If the milk coagulates well, you can keep it as a culture medium, but it cannot be used multiple times because aseptic operation cannot be guaranteed at home. The culture medium can be placed in the refrigerator. If the film at the mouth of the bottle bulges and gas is produced inside, it means that gas-producing bacteria have entered the bottle and it can only be eaten and cannot be kept as a culture.
