Take the whey and heat it to 200 degrees plus (F of course). If your whey is acidic enough, little specs of the albumen will start to precipitate out once it gets to around 200. If this does not happen, add a tablespoon or two of white vinegar. Once the albumen starts to separate, maintain the heat for a few minutes so it all has time to set up, then pour through a very fine cheese cloth. It usually takes several hours, if not overnight, to drain completely.
Salt if you like, then use it however you like. I usually get 1/2 - 1 cup of finished ricotta from the whey produced by a gallon of milk, after cheese making.
The cheese cloth they re talking about there is REAL cheese cloth, not the gauzy stuff they sell in the grocery store. And if you want to try ricotta, one source I saw said to let the whey sit over night to increase acidity.
