Grandma’s Chocolate Pie

My grandmother served chocolate meringue pie after Sunday dinner each week, usually with an apology it was “too runny” or something else was wrong with it.
Ingredients
½ c. cocoa
¼ cup cornstarch
3 egg yolks
1 ½ c. sugar
¼ tsp. salt
2 c. milk
1 tsp. vanilla



Directions
This recipe does not have meringue on it. You could make the meringue if you want.
Mix cocoa, cornstarch, beaten egg yolks; sugar and salt and vanilla, then add milk gradually, while stirring in a pot over med-high heat. Cook until thick, beating it smooth. Pour into a pre-baked pie shell. Put in the fridge to chill
