Using a pan with a lid, add sugar, corn syrup, water and salt. Stir to combine, cover and cook over medium heat for 10 minutes. No need to stir. Remove lid after 10 minutes and set aside.
While waiting, beat the egg whites with an electric mixer on highest setting until stiff peaks form. Set aside but whip again on high before the next step.
Set the electric mixer to low speed. Very, very slowly in a very thin stream, add the syrup mixture to the egg whites. It should take approximately 5 minutes to complete. Don't add too quickly!
Once the syrup mixture has been added completely, turn to the highest setting. Whip until you achieve a thick consistency. This will take approximately 10 - 15 minutes. Remove bowl from mixer.
Add chocolate chips to the mixture and stir until completely melted.

The easiest method for cleaning is to add water to the pan and heat over high heat. Let it cool some so you don't burn yourself. Clean the sticky mess with the warm water.
