The most favorite of all North Indians is Paneer (cottage cheese)
and if wish to make it quickly at home then...
Put to boil 1 litre Milk to which have to add 11/2tsp vinegar or citric acid diluted in water. Add to the milk.
When the milk curdles take it off the heat.
Pour into a cotton/muslin cloth and tie it with a tight knot.
When all the water is drained then put heavy weight on the tied paneer for 1 to 2 hours, paneer is ready..
From one liter milk you can get 150 grams paneer[ approximately ]
