Delicious and Healthy Plain Yogurt

Heat the skim milk in a saucepan until the first small bubbles start forming along the edges. Turn off the heat.

While the milk heats, mix the plain yogurt with the skim milk powder in a separate bowl. Let this mixture reach room temperature.

If a film or skin forms on the surface of the heated milk, skim it off.

Check the milk temperature. The ideal range for inoculation is between 42°C and 45°C. If you don't have a thermometer, insert a cleaned finger; you should be able to hold it in for 10 seconds without feeling like it's burning.

Add the yogurt and milk powder mixture to the warm milk and mix well.

Wrap the pot completely with a towel and place it inside the turned-off oven to incubate.

Let the yogurt incubate for 8 to 12 hours, or until the next day, without opening the oven.

After the incubation time, whisk the yogurt vigorously with a whisk to restore its creaminess.

Divide the yogurt into jars, filling them only halfway, with the intention of later adding toppings like granola and fruit.
