Best Ever Lemon Pie

1 baked deep 9-inch pie shell
1 1/4 cups sugar
6 Tbsp. cornstarch
2 cups water
1/3 cup fresh lemon juice
3 egg yolks (reserve whites for meringue)
1 1/2 tsp. lemon extract
2 tsp. vinegar
3 Tbsp. butter

Mix sugar and cornstarch together in the top of a double boiler.  Add the 2 cups of water.  Combine egg yolks with lemon juice and beat until well mixed.  Add to the sugar mixture.  Cook over boiling water until thick, about 25 minutes.  This does away with the starch taste.  Now add the lemon extract, butter, and vinegar and stir thoroughly.  Pour mixture into pie shell and let cool.  Complete with meringue.

1 Tbsp. cornstarch

2 Tbsp. cold water
1/2 cup boiling water
3 egg whites
