Add whole milk, heavy cream, and salt to the pan and bring the milk to a boil. Keep stirring occasionally while boiling to avoid the milk from scorching.
Once the milk comes to a boil, remove the pan from heat and stir in lemon juice. The milk will curdle immediately and whey will separate from the curd. Let it rest for 2-3 minutes.
You can also wrap the drained ricotta in the cheesecloth and press it with something heavy and refrigerate it overnight to get paneer, ricotta salata, queso fresco, or other fresh farmers cheese.
