Step 1

In a large mixing bowl, add the separated egg whites and 2 tsp lemon juice.

Step 2

Slowly mix with a wire whisk.

Step 3

Add the powdered sugar 1 cup at a time until you reach the desired consistency.

Step 4

Mix on medium speed until well blended.

Step 5

To add coloring, I recommend using only gel food colors as they add brilliant color without thinning your frosting.For piping, I add all four cups of sugar and blend until stiff glossy peaks form that do not disappear into the bowl after 3-second count. If using for "flooding" or filling I only add 3 cups.

Step 6

If you have thickened the frosting too much add the milk a small amount at a time until you achieve the consistency you're looking for.
