Make lemon juice. You can use a manual juice squeezer as we did, or an electric juice maker for this purpose.
Pour milk into a large pot, and bring it to a boil over medium heat, stirring slowly.
Reduce the heat to low, let the milk boil for 2 minutes, then stir in lemon juice.
Leave the milk to rest without stirring for about 5 minutes until it curdles.
Meanwhile, place a sieve over a bowl or another pot and cover it with cheesecloth.
Transfer the curds into the cheesecloth.
Leave the curds to drain.
Dissolve salt in a cup of lukewarm boiled water, pour it over the curds, and leave them to drain for 30 minutes.
The cheese will still be a bit wet. Squeeze cheesecloth to remove the remaining whey.
Wrap up the cheese with the cheesecloth and place it in a medium-sized bowl. Place a small plate and a jar or bottle with water on top to press the cheese.
Refrigerate for 8-10 hours.
Serve cold or in recipes as needed.
