Quark - Making Cheese In a Bottle
This has to be one of the craziest or laziest ways to make cheese. You don't even take the milk out of the bottle.
Fresh, homemade Quark makes the best cheesecakes.
While Non-Homogenised milk is preferable, a good quality Homogenised milk or Long Life Milk will work too.
Buy a Quark & Buttermilk Kit.
