Frozen custard is just ice cream made with milk, egg yolks, sugar and flavorings cooked like a custard sauce and churned in a ice cream machine. No gum arabic, no artificial thickeners or egg substitute. Its a lot like gelato than regular, out of the carton ice cream. Theres a real difference and its very delicious. I think the "frozen custard" puts people off...try it, I guarantee you'll love it. My favorite is vanilla.
