In a large saucepan, add the milk and the salt.
Turn on the heat to medium to low power and let it heat up.
Meanwhile, peel a green apple, grate it using the large holes on the grater and set aside.
When the milk starts to boil, mix and add the grated apple.
Add the ground cinnamon and mix again until well-combined.
Then add the juice of one lemon and keep mixing until the liquid part separates from the curd.
Now, using a sieve, remove all this curd from the saucepan, transfer it to a cloth strainer and squeeze out the excess liquid.
Transfer to a plastic pot or a cheese container, take it to the fridge and let it chill for at least 6 hours.
Serve.
