Close pressure cooker according to the manufacturer's instructions and place it over medium heat until it starts to release pressure and then reduce to low. (see Picture 3)

(It is important that the burner size is suitable for the diameter of the pan: too big and heat too strong; too small - heat too weak.)

Let it cook for 2 hours and 45 minutes. Turn off the heat and release pressure according to the manufacturer's instructions.

Carefully remove cans from the pressure cooker and let them cool to room temperature.

IMPORTANT: DO NOT OPEN cans while hot or warm !!! Cooked condensed milk will be under pressure and once you open the lid it will spill everywhere.
