3 Tablespoons yoghurt maker culture
1 1/3 cups powdered milk
Make like you would in the yoghurt maker (fill 1/2 way with water, put the lid on and shake, then fill all the way with water and shake again then fill the yoghurt maker with boiling water to the baffle)
We've always got powdered milk in the cupboard for emergencies and a bag of powdered milk from Aldi is so much cheaper than several sachets of yoghurt culture.
I made it this way for the first time last night and it set even better than usual. I like the fact that it is less sweetened than other yoghurts and you can add your own fruit to it.
