Heat one half gallon of whole 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.
Squeeze the whey from the cheese curds into the sink or colander.
After you have removed as much of the whey as possible, place the cheese curds into a bowl and break into desired size pieces.
Add up to ½ teaspoon salt if desired.
Store in the refrigerator in an airtight container for up to 7 days.
Notes
This recipe yields about 10 ounces of cheese curds.
