Tips For Storing or Using Left Over Egg Whites
Store Individually - Drop one egg white in each section of a ice cube tray and freeze. Remove the egg white cubes and store in a freezer style zip-lock bag.
Store in Quantity - If you have large quantities of egg whites pour them into an airtight container and freeze. Make sure to measure the whites and mark the container appropriately. To use, remove the container from the freezer and allow to thaw overnight in the refrigerator.
Facial - Beat one egg white until it is frothy. Spread it all over your face. Allow the egg white to dry. You will feel your skin tighten as the egg white dries. Rinse it off. Your skin will have a nice tingly feeling. Do not try this if you are allergic to eggs.
