Nestle's condensed milk water to drink, in fact, there is no big requirement for water temperature, boiling water to flush on it, because if too cold water, then melt very slowly, cold water in fact can also be filled, but filled not so good, drink milk or a little bit of temperature, flush will be better.

The proportion of water and milk, in fact, mainly in accordance with your own taste, you take a cup, the milk is about 1/5 of the bottom of the cup, and then you can put a large cup of water, I think this proportion of the milk out of the drink will be better, but if you like a little thicker, you can put a little bit more milk, or a little bit less water can be.
