This rich custard makes a sumptuous base for any homemade ice cream, simply add flavorings to taste. Admittedly it is a little time-consuming and takes a bit of patience, but custards were most likely the basis for the rich, unforgettable ice creams your grandmother made on the porch when you were growing up.
Combine 1 cup sugar, 1 tablespoon cornstarch and a scant teaspoon salt in a saucepan. Gradually stir in a quart of half-and-half, stirring constantly and place over low heat. In a large bowl beat together 2 large eggs and a tablespoon of pure vanilla extract until whites and yolks are thoroughly blended. Add this mixture very slowly into the half and half, stirring constantly and gradually increasing heat until thickened. It should have the consistency of eggnog. Stir in a pint of whipping cream and remove from heat. Refrigerate for 45 minutes to cool, then add fruit, nuts and/or flavorings and sugar to taste, place in your ice cream freezer and process according to directions.
