Have you thought of trying a non-electric yoghurt maker? I have one made by EasiYo, and it is basically a large plastic wide-necked flask with a baffle inside, which you half-fill with boiling water. The live yoghurt mixes are powdered, and you just shake up a sachet with tap water in the plastic screw-topped jar provided, and lower it into the flask. Just put on the lid, and about 8 hours later you have your lovely yoghurt! (Good for you, too, with lots of yummy bacteria). It really is child's play to make, and my other half loves the Greek variety for breakfast every day. Not sure how easy it is to get the mixes in France though, - have a look at the website for distributors www.easiyo.com. I know Lakeland amongst other places sell it in the UK, but it originated in New Zealand, invented by a dad with a large family in his garage. (I mean he invented the yoghurt in his garage, not that his family lived in there!!). Hope this helps, Mary
