This simple, unpretentious Nicaraguan custard consists of milk, sugar, butter, egg yolks, and cornstarch. It is lightly flavored with cinnamon and vanilla. The custard has an unusual consistency, so it can be sipped or consumed with a spoon. Atolillo can be served as a dessert in small bowls or glasses, but it is also used as a topping for various cakes such as Pio V.
