zipper bag ice cream

There was a recipe for ice cream you make in ziploc bags but I can't find it does anyone have it?? Thank you!

Ingredients:

1 Scoop Vanilla flavored protein powder
Four-Five Packets Splenda

½ teaspoon Vanilla Extract
3/4 cup skim milk or fat free milk
2 tablespoons FF Half and Half
1 egg
Sprinkle Nutmeg
Table Salt
Ice (enough to fill half a gallon sized Ziploc bag)
1 sandwich-size Ziploc bag
1 gallon-sized Ziploc bag
In blender or bowl combine splenda, protein powder, vanilla extract, nutmeg, skim milk or FF milk, 1 egg and blend or mix with mixer.  Pour mixture into the sandwich bag. Seal the bag tightly. 

In the gallon-sized bag, add ice cubes (or fill half the bag with ice) and add 6 or more tablespoons of table salt.

Place the sealed sandwich-sized bag into the gallon bag in the center of the ice.  Seal the gallon bag. Shake the entire contents for at least 4 minutes (shake longer for harder ice cream). Once desired hardness has been achieved, remove smaller bagg and rinse thoroughly with cold water (if you miss this step you may wind up with salty ice cream!)

Thank you thank you thank you ~ making it tonight!!

The egg is used raw? This recipe sounds delicious, but I am quite concerned about consuming a raw egg!
