Making yogurt is actually very simple. Step 1: First, prepare raw materials such as fresh milk and yogurt starter (or plain yogurt bought in the supermarket). Remember that it must be plain old yogurt, and the fruit flavor is mixed with food additives, so it cannot be used. Step 2: Wash the yogurt machine with hot water for disinfection, dry it or wipe off the water with a clean cloth. If there is water, it will affect the fermentation effect. The third step is to heat the fresh milk without boiling or being too hot. You can add sugar according to your own taste and adjust the acidity with sugar. If you like sour food, you don't have to put it. Just touch it with your hand, add yogurt starter or plain yogurt, and stir well with a spoon or chopsticks. Step 4, pour the evenly stirred fresh milk into the yogurt machine and start it for 7-8 hours. When the time is up, you can wait for 20 hours. The prepared yogurt will taste better after being put in the refrigerator. You can add sugar, honey or other jam when eating. ? The taste of plain yogurt will be different from that bought in peacetime. After all, there are no additives. I hope you can make your own delicious yogurt! !
