Did this yesterday for the first time, I was surprised how simple it was.
4 cups whole milk
2 cups heavy cream
1 1/2 teaspoons kosher salt
3 tablespoons white wine vinegar
combine the first three ingredients and bring to a boil, remove from the heat and stir in the vinegar. Wait 1-2 minutes for the mixture to curdle and pour it all into a strainer lined with a couple layers of cheesecloth. Let it sit for half an hour and remove the curds from the cheesecloth and discard the liquid (whey) that you drained off. Yields about a pound of ricotta.
