What are you think about milk powder for these days?

tHERE ARE MANY DIFFERENT BRANDS... WHAT DO YOU MEAN?

I always keep instant powdered milk. I use it some times in baking.

It is very common in my country to use powdered milk instead of the fresh one.
UHT processed milk is also common.
Fresh milk is available, but it is less popular because it is more difficult to store.
The milk container is seldom more than 1 liter (ca. 0.25 US galon).

my sons like it more than packed milk...I like too and some times add it to tea

In my country, fresh milk is readily available....I have always used it, and have only ever used powdered/uht milk when I went camping and was miles (literally) from a shop. I didn't like it then....its flavour/texture may have changed now......
