Check out my Instructable for making Great Mozzarella Cheese. You will find it at:
There are tons of Mozzarella Cheese recipes on the Internet. I checked a lot of them out and perfected my own recipe and made an Instructable for it to make it as easy as possible to make Mozzarella Cheese. It seemed like a lot of the recipes I found either left out a step or didn't explain it very well.
Unlike Mozzarella, Ricotta Cheese seems to be almost 100% foolproof.
There are recipes out there to make Ricotta from milk, but this lets you get everything possible out of that gallon you used for the Mozzarella.
Things you will need:
1. Leftover Whey
2. Large bowl
3. Reusable coffee filter. You can also use a clean cloth.
4. Large Strainer that you used for the Mozzarella
5. Small bowl to put the final product in
Step 1: Heat the Whey
Some people suggest letting the Whey set out overnight. I have tried that and also started it right away and haven't noticed any difference.
Turn the heat off and let it cool down some. After a little while, if there is stuff floating on top stir it so that it sinks to the bottom. This will help later so you can just strain most of the liquid and it won't clog up the filter so fast.
