Cool and sour homemade yogurt

Overview

How to cook Cool and sour homemade yogurt at home

Prepare 1,000 grams of original pure milk. Each bag of pure milk costs 1.5 yuan. Each bag is 200 grams. 5 bags are enough.
The lactic acid bacteria I use to ferment the yogurt can be purchased in Taobao stores. 1 pack contains 1 gram, and 1 gram can be used to ferment 1,000 grams of pure milk.
The container used to hold milk should be very clean, sterilize it by rolling it in boiling water, and then let it dry naturally. Add pure milk, lactic acid bacteria and 50 grams of powdered sugar to the container, and stir thoroughly for 1 minute to allow the powdered sugar and lactic acid bacteria to dissolve. If you think the calories are high, you can reduce the powdered sugar or add no powdered sugar, but the yogurt without powdered sugar will be a bit sour.
Pour the milk into the container, cover it with plastic wrap, put it in the oven and set the oven to fermentation function at 40 degrees for 6 hours. After the fermentation is completed, the yogurt should be placed in the plastic wrap of the refrigerator. Drink it within 2-3 days.
