Pour 2069 g whole milk into a wide, heavy-bottomed pan and heat until it reaches a rolling boil.
Take the pan off the heat and let the temperature drop to 49°C / 120°F.
Gradually drizzle 162 g white vinegar over the surface of the milk, stirring steadily for roughly 3 minutes until curds separate from the liquid whey.
Set a muslin-lined sieve over the sink and pour the contents of the pan through to drain off the whey.
Gather the cloth by its corners and press gently on the curds until the liquid escaping begins to look milky.
Turn the warm curds out onto a flat surface or tray and work them thoroughly with the heel of your hand to break down any grittiness into a smooth dough.
Allow the chhena to cool, wrap it securely in foil, and chill in the refrigerator for up to 24 hours.
