We had something about yoghurt on here:

http://www.jamieoliver.com/forum/viewtopic.php?id=76580

There are also a few links about this.

go to the search button on the left and look for homemade yogurth you'll find many threads and tips
I do mine with two tbsp of full fat plain yogurth added to 1lt. best milk I can find and let it stand covvered with a shawl/scarf on the plastic wrap for at least 8 hours, not tremmbling on the fridge ..... and it works, then you can put it in the fridge, or even drain it through a musseline cloth on a colander (for a few hours in the fridge) and get a thick greek yogurth
good luck and try again (my mentor cuoco Roberto says every recipe has its own number of failures to go through before you dare saying you know how to do it properly   )
let's know how it goes we'll  for you

Here's how I do it:  http://www.keeperofthehome.org/2011/04/ … urt-2.html

I just use a 1/2 cup of yogurt from the last batch as my starter. To get started on your first batch, you can just buy live culture yogurt from the grocery store to mix into the milk. I started with organic whole milk plain yogurt with my first batch.

Thanks - I love (almost) any recipe that lets me use my crockpot and free up some time/space in my kitchen.
