Creamy Vanilla Pudding

I usually make this in the microwave.

1/3 cup sugar
2 tablespoons cornstarch
1/8 teaspoon salt
2 cups milk
2 egg yolks, slightly beaten
2 tablespoons margarine or butter, softened
2 teaspoons vanilla

Mix sugar, cornstarch and salt in 2-quart saucepan. Stir in milk gradually. Cook over medium heat, stirring constantly, until mixture thickens and boils. Boil and stir 1 minute. Stir at least half of the hot mixture gradually into egg yolks. Blend into hot mixture in saucepan. Boil and stir 1 minute. Remove from heat; stir in margarine and vanilla. Pour into dessert dishes. Cool slightly; refrigerate. 4 servings.

Chocolate Pudding: Increase sugar to 1/2 cup and stir 1/3 cup cocoa into sugar mixture. Omit margarine.
