If the milk is good,almost probably good milk can find in Australia,, if that is your wish ate certain point, you can heat it until is hard(it kind of start to feel burn), to stay more than 10 seconds or around with finger immerse in milk.

Maybe for 3 liters of Milk you can use 2 around 200ml plain "natural" white yougurt cheaply sold.

I add honey most everyday, once a month brown sugar, or for variety aswell sugar cane syrup(what is superb, I have to say) on ocasions. First time better use only 1 liter of Milk only, to avoid waste if the mission goes unplannedly, for lack of training.

:for flavor: Is good for kids add redberries, or other color small berries, for adults, for magnesium, Almonds.
