Set a fine-mesh strainer or colander over a large bowl. Line the bottom with a double layer of cheesecloth. Place the ricotta on the cheesecloth-lined strainer and cover with the overhang of the cheesecloth. Placing a dish over the cheesecloth-covered cheese applies a small amount of pressure which encourages additional moisture to be released. After an overnight stay in the refrigerator, the cheese is now ready to be used.
