You probably did it just fine,

Here are a few tips that suggest how we do it.

Place meat into water and start to cook it. After it stars to boil, you will notice this foam type stuff start to float on surface. Spoon it off and discard. (I call it mung

Once there is no more mung, then add vegetables, salt, and pepper.
