I want to make my own cheese. How do I get started?
Making Mozzarella is not fantastically difficult, but certain things during the process are critical, probably the most important is temperature. 

If it's your first time making cheese, you might find the buying a 'starter kit' the easiest way to get up and running. These will provide you with all the important items you needm such as rennet. If you feel brave, then you forego the kit and dive right in.   

For Mozzarella try to find Buffalo milk, which is what 'proper' Mozzarella is made from. It's lower in cholesterol than cows milk, has more protein and makes a much richer cheese. If you can't get Buffalo milk use the best full fat, non-homogenized milk you can find.  

Here's a recipe I've used before MOZZARELLA

Here's a link with the differences between Buffalo milk and cows milk

Cow Milk vs Buffalo Milk

Whilst it's quite possible to make virtually any variety of cheese at home, some cheeses, such as blue cheese, require a place to develop at the correct temperature and for quite long periods of time.  ideally, this would be a temperature around 10c with a humidity around 70% and a time for maturing at around 2 to 3 months.

Here's a good place to start:
