Royal Icing

The perfect icing for decorating cut-out cookies. It dries quickly and very hard.

2 egg whites (to avoid bacteria, I use re-constituted, dried, pasteurized egg whites)
3 cups confectioners sugar
1 tablespoon lemon juice (I’ve skipped this ingredient before and it worked just fine)
1/4 tsp salt

Combine egg whites, sugar, lemon juice, and salt in a mixing bowl. Beat at high speed for several minutes, until the mixture holds soft peaks. Frost cookies and let air dry completely before packing in an airtight container.
