- Make a batch of yogurt as you have been doing.
- Then, when ready to make your next batch, fill the container with milk made up from powdered milk.
- Add 2-3 dessert spoons of your last batch of yogurt. Shake well.
That's it. Then put it in the thermos/hot water as per normal. When it is ready, we sweeten it with a spoonful of sugar or honey and sometimes flavour with vanilla or fruit.
- the water needs to be good quality, we use rain water but we don't boil it
- it may work using normal milk rather than milk powder, but we can't get fresh milk and have never tried it
- we also make it in empty plastic jars (the large peanut-butter jars), they are a bit smaller than the container that comes with the yogurt maker and so we add less hot water to the thermos
- yogurt can still be used to start a new culture if it has been in the fridge for up to four or five days
- yogurt is live bacteria culture... I'm not sure what that means for pregnant women as it is usually recommended that they avoid foods with live bacteria. Yogurt bacteria are harmless themselves (it fact, are supposed to be good for your gut) and yogurt itself is safe in pregnancy, I'm just not sure about when you make it yourself because you are creating perfect conditions for bacteria to grow and I don't know whether the harmful bacteria would/could also grow.
