Half price for this very simple yoghurt maker.
The concept is to make yoghurt with water and their sachets, put it in boiling water bath for 6-12 hours, and the outcome is yoghurt.
I find their sachets to be overpriced and not very nice. So the real bargain is combining this with 1.5 cups of milk powder (from a $5 bag) and a "starter" yoghurt of your choice, I use Jalna, which even works from frozen. Then flavour as you wish or leave as is. Benefit is the vastly superior bacterial culture (healthier) and controlling additives. Plus each batch of ~1kg yoghurt costs me somewhere between 50c and $1.
Great informative post. Thanks
