This item contains six sachets of powder that is mixed with water to produce a total of six kilograms of yoghurt. The process is very straightforward, and once you own an easiYo yoghurt jar and yoghurt maker you can produce high quality tasty yoghurt at a lower cost than with established brands of prepared yoghurt in the supermarkets. The sachets are easy to store, and it only takes minutes to prepare the yoghurt. My approach is to prepare the yoghurt in the morning, let it incubate through the day and then put it in the fridge to set overnight. It is a treat to eat the freshly made yoghurt in the morning.
