We eat yoghurt most nights, so I thought it was time that we made our own.

It’s effectively just soured milk, which is why it’s so often mixed with strong flavours like fruit or toffee – they temper the sour taste in your mouth.

Now after a lot of hunting around online it seems that there is no definitive recipe for home made yoghurt – you just make your milk go off by introducing some ‘culture’ and take it from there. The easiest way to do this is to warm is slightly and then spoon in a pot of live yoghurt you’ve bought from the supermarket.

We used Yeo Valley for no other reason than it being the only ‘live’ one we could find in our local store.

Now it struck us as cheating to do this. Effectively you’re just taking some yoghurt and making more yoghurt, but unless you can find some other way of sourcing that bacteria there’s not much you can do. So, let’s look as it another way. By making our own yoghurt like this we need buy only one pot and have an almost limitless supply as you simply top up your pot with some more milk every time you take some out. The result, of course, is less waste as you’re not forever buying plastic cartons from the shops.

Plus, of course, it’s cheaper.

So, we poured 750ml of milk (1.58 pints) into a saucepan and heated it very gently, just until it was warm to the touch. We certainly didn’t want to boil it as that would probably kill the bacteria. When it was comfortable to keep our finger in it for some time (around 30 degrees Celsius – 85 degrees Fahrenheit) we took it off the heat and stirred in the live yoghurt.

We cheated a little bit by using a digital thermometer, but only because this is the first time we’ve done it and we wanted to be careful.

Now all we need to do is keep it warm and wait. We’ve put it close to a tepid radiator to keep it to cosy without it getting too hot and are looking at it every day. It’s been 24 hours so far, and not much has happened, beyond some thickening up at the bottom of the jar. We’re taking that as a good sign.

If all goes well, the yoghurt should take about three days to work its magic. Come back and see how we get on.
