  1. Place all of the ingredients to make 1 package of sauce mix in a small zippered bag or mylar bag.
  2. Place an oxygen absorber in the bag.
  3. Fold the bag over to remove as much air as possible and seal it if you are using a plastic bag. If you are using a mylar bag, seal it as normal.
  4. Set the bag aside to put in the same container as the powdered milk and dehydrated potatoes.


*The amount of cheese depends on your personal preference. I use 1/4 cup.
