Set aside a large heat-proof bowl with a cheesecloth-lined strainer ready for straining.
In a large heavy-bottomed sauce plan, bring the milk and the cream to a simmer (not a boil) stirring constantly. Make sure to use full-fat milk here or it won't curdle. You can also use all milk.
Reduce the heat to medium and gradually add the lemon juice while stirring until the curds separate from the liquid like magic!
Pour the mixture through the cheesecloth and let drain for 15 minutes.
Process the curds in a food processor for a few minutes until smooth, adding a little of the whey liquid or cream if it's too thick. Season with salt to taste or add the flavors of your choice! You can use it right away or refrigerate until ready to serve- the cream cheese will thicker in the refrigerator. The cream cheese will keep refrigerated for 7-10 days.
