Yoghurt Making - Attempt 1
On Saturday I made my first batch of yoghurt with my new (second-hand from ebay) yoghurt maker. It was an outstanding success and astonishing easy to do.
First, you need the basic ingredients: milk, milk powder and some bacteria. You need the milk powder to increase the amount of protein in the milk as cow's milk will make a very runny yoghurt without it (apparently). I've used UHT milk to eliminate one step of the process. If you use normal pasteurised milk, you need to heat it to 110 degrees Celsius to kill any rogue bacteria.
The yoghurt bacteria can be sourced either from yoghurt with live cultures or from some pure yoghurt bacteria starter. I got some starter from Martin at work. The important bit about the bacteria no matter what kind you have, is adding it at the right point. According to the Internet, the right point is when your milk is at 43 degrees Celsius. This requires a thermometer.

After you've added your bacteria, you need to keep the whole mixture warm for at least four hours. Thanks to my yoghurt maker this was easy. Simply fill the jars, put the lids on, and switch the machine on.
Once they're done, they will be set and will probably have a little bit of liquid (it's the whey) sitting on top of the yoghurt. There are two options at this point, put the yoghurt in the fridge for enjoyment later. Or if you'd like thicker yoghurt, you can strain the yoghurt in some muslin in the fridge as this drains off the whey.
