Paneer is an essential ingredient.
Okay, here's how it worked for me. I made the recipe as it is written using whole milk and got some curds (about 3/4 cup) with remaining liquid that looked like 2% milk, not whey. It seemed like I could get more out of it, so I cooled the mixture down to room temperature, then heated it to boiling again and added a tablespoon of white vinegar as suggested by another reviewer. It curdled beautifully leaving a clear whey and more solids than the first attempt. My advice is to go straight for the vinegar as the acidity of lemons may vary from one to the next. The paneer tastes excellent with a nice firmness that held its shape when cut. - 06 Jan 2008 (Review from Allrecipes US | Canada)
Paneer is quite easy to make. Definitely requires whole milk. One thing this recipe doesn't mention is that the milk has to curdle. This occurs once you put in the lemon juice. I have seen it not curdle, perhaps due to less acidic lemons. Lemon can be substituted with white vinegar, especially if your lemons won't cause it to curdle. Toss some fresh cracked peppercorns into the curdled milk in the cheese cloth and stir before hanging for peppercorn paneer. - 23 Oct 2007 (Review from Allrecipes US | Canada)
Being an indian, we use regular milk in making paneer. I am assuming that Dostanden ment to put that in the recipe. Usually the higher the fat content in milk, the better and more paneer you will get. - 25 Mar 2006 (Review from Allrecipes US | Canada)
