I may of had a yoghurt failure too. I followed the EDC with 10% fat greek yoghurt as my starter. Put it in a pyrex glass dish with a lid but didn't put it in a cool oven because my oven has an open gas flame. Left it in the pantry for 5 hrs. Just took it out after 5 hrs to put it in the fridge and its thickened to drinking yoghurt consistency but no thicker. Will leave it overnight in the fridge and see the result in the morning.
Should I have put it in the thermoserver instead to set?
Do you need the 'cool oven' if you have a thermoserver?
What can I do with the yohurt I have if it stays runnier than yoghurt should be? Suggestions welcome. Thanks!!
