Marlene's Lemon Meringue Pie

Butch's sister, Marlene, makes the world's best Lemon Meringue Pie and I am not the only one who thinks so. My friend Peggy says it makes her mouth water just thinking about it. Yesterday at crafts we were discussing her pie and I said she most likely has the recipe in her head and wouldn't be able to tell us. But I emailed her and asked and she shared her meringue recipe with us this morning. So here is Marlene's Meringue.
From Marlene:

It’s a strange recipe, but works for me –

                                    Never Fail Meringue

                                    1 TBLS. Cornstarch

                                    2 TBLS. Cold water

                  Blend cornstarch and cold water in a saucepan

                                    ½ cup boiling water

                  Add boiling water and cook, stirring until clear and thickened,

                  Let stand until COMPLETELY COLD.

                                    3 egg whites

                                    6 TBLS. Sugar

                                    1 tsp. vanilla or lemon flavoring

                                    Pinch of salt.

                  With electric mixer on high speed, beat egg whites until frothy.

                  Gradually add sugar, and beat until stiff but not dry.

                  Turn mixer to low speed, add salt and flavoring

                  Gradually beat in cold cornstarch mixture.  Turn mixer
