In a large bowl, whisk sugar with eggs and yolks for 1-2 minutes. Whisk in cornstarch. Set aside.

In a medium saucepan, heat 1 cup of the half-and-half over medium heat until it comes to a simmer. Slowly, whisk hot half-and-half into egg mixture. Pour entire mixture back into the pan and cook on low heat, stirring constantly for about 3-4 minutes, until thickened. The mixture will coat the back of a wooden spoon when thickened.
