Pour milk, heavy cream and salt into a large non-stick pot. Place it over medium heat.
When the mixture comes to a simmer stir in the lemon juice, one tablespoon at a time.
Stir gently with a wooden spoon and turn the heat down to medium-low. The mixture will start curdling. Turn the heat off and allow it to sit for 5 minutes.
Once fully curdled, pour it into a large strainer or sieve lined with cheesecloth. Allow it to drain for 10 minutes if you want the ricotta cheese to be soft. But if you want a firm cheese, then let it sit for an hour.
Enjoy this freshly made ricotta cheese with bread or add it to pizza, pasta or lasagna.
