The yogurt maker arrived, its very simple, not sure why but I was expecting something far more complicated than this. Apparently all I need do is put a couple of teaspoons of live fresh yogurt into the glass containers, top up with sterilised milk and plug in. It doesn't have a timer, you just plug in, switch on and time it, then switch it off. It doesn't seem to be a very exact science, the instructions read 'between 8-9 hours if the milk is from the fridge, between 6-7 hours if the milk is pre-heated and then cooled. Think I'm going to wait until the weekend to try this out. I bought a timer for it and I'm sure once I've figured out how long it takes I'll be able to go away and leave it; but I think I'll be around the first time its in use. I'm looking forward to this, home made yogurt sounds wonderfully wholesome.
