Foot Warmer Homemade Yogurt
1.
Prepare a foot warmer.
2.
Prepare 1000 ml of pure milk, a box of yogurt used as a strain, and pay attention to buying yogurt in the refrigerator in the supermarket.
3.
The container is scalded with boiling water for disinfection and sterilization. I use a casserole, which has better heat preservation performance.
4.
Pour the yogurt as the strain into the casserole.
5.
Pour the milk and mix well.
6.
The small holes on the lid of the casserole are sealed with plastic wrap, and the lactic acid bacteria fermentation does not require oxygen.
7.
The foot warmer removes the cotton cover and pads a pair of old jeans to prevent the bottom temperature from becoming too high.
8.
The casserole is placed on top of the jeans.
9.
Turn on the foot warmer switch and push it to the low temperature gear.
10.
At the beginning I covered a foam box, but because the foam box was a bit small and the bottom was not sealed, the thermometer showed 14°C after 1 hour, so I changed the old cotton coat to cover the casserole and the foot warmer. After sealing, the temperature rose to 35. ℃.
11.
After 8 hours of fermentation, the yogurt is ready. When it cools, put it in the refrigerator to make it thicker.
12.
There are many ways to eat yogurt. You can eat it with fruits, nuts, soak oatmeal, mix salads, and so on. What I do is sugar-free, you can add sugar or honey if you like sweets.
Tips:
① Buy the yogurt used as strains from the refrigerator in the supermarket. Don't buy the room temperature yogurt. The active bacteria of that yogurt have been killed by the high temperature.
②It can also be made with yogurt bacteria powder, the effect is the same, please refer to the package instructions for the dosage.
③The fermentation temperature is generally 30~40℃, lactic acid bacteria are the most active, and it may be scalded to death if it exceeds 40℃.
④The fermentation time is generally 8 hours, but the specific conditions depend on the activity of lactic acid bacteria, the fermentation temperature and other conditions will fluctuate, pay attention to observation.
⑤ The fermented yogurt should be kept in the refrigerator to make it thicker.
⑥I make sugar-free yogurt. For sweet ones, you can add sugar to the milk and ferment together, or you can add sugar and other sweeteners when you eat.
