Simmer pork in water for 40 minutes. Very low heat. Half a gallon water. (Approx 2 liters of water)
Tun off the heat, put lid on top and wait until the pot cools down. 3 hours or so.
Put ginger and sugar in and simmer in low heat for another 30 mins. Skim the liquid as you cook.
Add soy sauce and simmer for another 20 mins in low heat. Skim the liquid.
Turn off the heat, put the lid on and wait until it cools down. 3 hours or so.
In a different pan, thicken the liquid to make it a sauce.
Eat. So soft you can tear the meat with chopsticks. It stays soft the next day if you keep it in the liquid. If you do so, reheat it and eat to achieve back the tenderness.
