Add chopped up chocolate to the milk in a double boiler and heat to melt. Beat until blended. Sift sugar, flour and salt together and add a small amount of the hot chocolate to it and stir. Now pour this mixture into the double boiler with the rest of the hot chocolate and stir. Add 2 T. butter to this and cook with constant stirring for 10 mins. Longer. Pour a small amount of this cooked mixture over the well beaten egg yolks while stirring vigorously to keep from cooking the eggs and immediately pour this back into double boiler and stir and cook until thick. Watch carefully. When starting to thicken, remove from heat and add the vanilla and stir. Cool in a baked pie shell for pie or in 6-8 pyrex cups for pudding, This method of pouring back and forth with stirring helps prevent lumps from forming. Meringue: 3 egg whites beaten with 6 T. sugar if wanted on pie. I prefer it plain with maybe a little vanilla ice cream on the side. Very rich and yummy!
