MERINGUE VINEGAR PIE

This is a very old-fashion recipe that my late mother had for years.

1 egg yolk
2 tbs. flour
1 cup boiling water
lemon flavoring
small lump butter
1 cup granulated sugar
2 tbs. strong vinegar

Beat together well the egg yolk, butter, flour, and sugar.  Add the boiling water and the vinegar stirring constantly.  Cook over low heat until thickened, add 1 tsp. lemon flavoring.  Place in a baked pie shell, cover with your favorite meringue and brown in the oven.
