Step 1

Use a stand mixer. It will change your life. You can make this using a hand mixer, but it just takes time. In a clean bowl (any grease on your bowl or utensils will ruin the icing -- egg whites hate grease!), beat the egg whites and salt on high speed until foamy.

Step 2

With the mixer still running, slowly add the sugar. Beat mixture until soft peaks form (when you pull the mixer out of the white mixture, you should get a little point that bends over).

Step 3

Bring the corn syrup to a boil over medium heat in a small saucepan. When the corn syrup comes to a boil, remove from heat.

Step 4

Slowly pour the hot corn syrup into the egg mixture while your mixer is mixing on high. Beat the mixture until stiff peaks form, about 5 minutes. Add the vanilla, and mix to combine.

Step 5

Use right away.
