Heat one half gallon of lactose free milk in a large heavy pot over medium heat to 190 degrees Fahrenheit, stirring occasionally.
Watch carefully to make sure the milk does not burn.
Once the milk reaches 190 degrees Fahrenheit, remove from the heat.Add 6 tablespoon vinegar or lemon juice with a wooden spoon. Stir well.
Cover the pot and allow to rest for 30 minutes.
While the milk and acid mixture is resting, place the cheesecloth or tea towel in a large colander and set it over a large bowl.
If using cheesecloth, use a double layer.
After 30 minutes, use a large slotted spoon to remove the cottage cheese curds from the liquid whey and place the curds in the lined colander.
Allow the rest of the liquid to drain from the curds into the bowl.
After the cheese has dried slightly, gather it up in the cheese cloth or tea towel and squeeze it tightly into a ball.
Run the cheese, still wrapped in the cloth, under cold water while continuing to squeeze the ball gently.
Once the cheese has cooled, unwrap the cheese curds and break into desired size curds (large or small).
Stir in ¼ teaspoon salt.
Add the lactose free cream or half and half a few tablespoons at a time, until you are at the desired consistency.
You may or may not use the entire ½ cup.
Add more salt to taste.
Place in an airtight container and store in the refrigerator for 5-7 days.
