Ace Pineapple

I believe you are referring to a food item known as "pineapple upside-down cake" that is sometimes referred to as "ace pineapple" in some restaurants in the USA.

Pineapple upside-down cake is a type of cake that is prepared by first caramelizing sugar and butter in the bottom of a cake pan, and then arranging slices of pineapple on top before pouring in the cake batter. Once the cake is baked and cooled, it is inverted onto a plate so that the pineapple slices are on top and form a decorative pattern.

This dessert has been a popular menu item in American restaurants for many years, and it is known for its sweet and fruity taste. The pineapple slices are often accompanied by maraschino cherries, providing a contrast in color and a burst of flavor.

Pineapple upside-down cake is typically served as a dessert, and it is often enjoyed with a scoop of vanilla ice cream or a dollop of whipped cream. Some people also like to sprinkle confectioners' sugar or drizzle caramel sauce over the top for an extra touch of sweetness.

If you have the opportunity to try pineapple upside-down cake, I would encourage you to give it a try. It is a delicious and satisfying treat that is sure to leave a lasting impression!
