With the "solubile" type of Orzo, there's no need to premix and add to the milk or water, you can just add it directly to the cup full of liquid (like instant coffee), but if you don't have "solubile", you'll want to make it the way I show below.

Heat the desired amount of milk in a small pot.

When the milk is hot, add the orzo mixture and stir well.

Continue to stir over medium high heat until mixed well. Add sugar to taste, if desired. I like a little bit of sugar in mine.

Serve hot in a cup or mug, or if making breakfast for a child, break up pieces of toasted bread into a bowl and pour the orzo over it.
