Place a sieve over a large bowl, line with a cheesecloth, and set aside.
In a large pot over medium-high heat, bring the milk, heavy whipping cream, and salt to a simmer, stirring constantly to prevent it from boiling over-- about 5 minutes.
Add in the white wine vinegar and continue stirring.
Allow the mixture to curdle-- about 2 minutes.
Strain the mixture through the cheesecloth-lined sieve and set it aside to drain for at least 20 minutes.
Use immediately or transfer to an airtight container and store in the refrigerator for up to 5 days.
Notes
If you don’t have white wine vinegar, substitute the same amount of freshly squeezed lemon juice.
This combination of milk and cream makes the creamiest ricotta! I highly recommend using both!
The milk needs to get hot enough to curdle— if you have a thermometer, check the temperature to make sure it is at least 190F before adding the white wine vinegar.
