One big orange or two small ones. They must be juicy.
Honey or sugar. 1-2 T.
2 T. Nonfat powder milk (this is what we would use when I was a kid) I used 1 scoop Nido milk powder. Purchased from the Mexican food isle. There are two kinds and they both come with a scoop and either will do. Or you can add 1/4-1/3 cup of milk. You can also make this drink without any milk.
1 cup of ice (crushed is best, but we only had cubes growing up and either way you may have one or two small ice balls in your drink. No big deal. Just go with it.) Use can use less ice if using liquid milk. You can also add about 1/4-1/3 cup of water if using powder milk.
I egg (yes, a raw egg is very nutritious and gives the drink a frothy texture)
5 ingredients. That's it. Peel your orange and put it into the blender. Add the ice, egg, milk, and your sweet of choice. Blend until mixed and frothy looking.
