Pour milk into a large saucepan. Heat milk to 185°F, stirring gently over medium heat. For best results use a cooking thermometer to check temperature.
Remove from heat. Stir in acid slowly.
Let sit 15–20 minutes. Do not stir.
Strain through fine cheese cloth, muslin cloth or nut milk bag — but don’t rinse!
Let drain only 10–15 minutes for soft runnier ricotta; longer for firmer, drier ricotta, 20-25 minutes.
Scoop into container and chill.
Creamier texture? Stir in 1–2 tbsp of cream after draining.
Once chilled, the curds firm up and blend together, giving you that ricotta-like smoothness.
See additional notes above for optional add ins.
Store in an airtight container in the fridge for up to 3 days.
