Push the cheese curd through a china cap or large strainer several times, breaking it up into small pieces. Place the broken up cheese curd into a pan with warm water, enough to cover. Knead the curd with your hands. Pour out 75 percent of the water. With a paddle or wooden spoon, press the water and cheese mixture together. Stretch the mozzarella carefully. Pour in boiling water. Knead and stretch the cheese more. Pour 75 percent of water out and add back, boiling water. Repeat this process and ball up mozzarella to create a smooth top surface, tucking the other sides underneath.
