There are instructions in the yogurt machine. My yogurt machine only takes 6 or 7 hours. Mine has a capacity of 1000ml of lactic acid bacteria. You can use the milk yogurt bought in the supermarket as a starter. Pour in a quarter of it. . You can use fresh milk or buy milk powder to make it. We use Nestlé milk powder to make it, and the effect is the same. We need to add more sugar, like 1000ml of sugar cubes. We need to put 14 sugar cubes. Later, we add white sugar, which is about the same. If you don’t want to add white sugar, you can add honey. Healthy~! If fresh milk is raw, of course it must be cooked. After cooking, it must be left to dry. Lactobacilli will die if it is boiled. It's almost the same as the ones in the supermarket. If it's too thin, it sometimes looks a bit like tofu curd, haha. The milk will thicken a bit. Step 1. Clean the machine 2. Pour in the milk 3. Add sugar and mix well. 4. Add yogurt or mushroom powder and mix well (a little bit can be used as a primer) 5. Put it into the yogurt machine. It will take about 7 hours. OK! 6. Put it in the refrigerator. It will taste better! Suggestion: Adding sugar before making yogurt can effectively shorten the fermentation time. Then you can add some fruit pieces, such as banana pieces, grape pieces, raisins, peach pieces, mango pieces, etc., and then ferment it. This taste will be super great. Yes, you can also add chocolate powder after making the yogurt. This will produce chocolate-flavored yogurt. You can also put it into a food processor with mango (or strawberry, pineapple and other fruits), ice cubes, etc. and crush it together. You can make delicious milkshakes and smoothies that are rich, mellow, fresh and healthy, even better than those famous brand yogurts! ! ! Hope it helps you
