This is how I make yogurt:

Step 1: Put 1 liter of milk mixed with 0.2 liter of Yogurt on a heating radiator at 11PM.

Step 2: Wake up at 7AM. Yogurt is ready.

What Yoghurt do you use in Step 1?

The first time, you can use a Yogurt without artificial flavor. Afterward, you can reuse the Yogurt made the first time. Or just use a common Yoghurt from the store. You can use less than 0.2L the first time because the artificial flavor mixed with the natural Yoghurt flavor will not taste that good. The second time and afterward you can use the Yogurt made the first time, the artificial flavor will be diluted.

EDIT: Warning, I do not know how many times can you safely reuse the Yogurt. I've reused the 'same' Yogurt several times without any issue, but please do your research. Of course, I store it in the fridge.

Yes, the original post seems a lot of extra effort to make it thick and set. My simple method:

1. Warm milk to 120°F in a pan with a spoon of yoghurt

2. Put in thermos flask 8 hours / overnight

3. Put in a jar and leave in the fridge until cool enough to enjoy
