1kg Easiyo yoghurt maker on special at Woolworths. Now $15. I’ve also found 1L glass jars like the coconut oil from aldi fit inside the thermos. An easy way to make yoghurt if you have a family who demolishes it like mine.
The yoghurt sachets are also on special $3.50 down from $4.50. Or just make Greek yoghurt using a small tub of Greek or natural yoghurt, water and milk powder.
