Step 1

Add the Ingredients - In a high-speed blender, add the pineapple juice, frozen pineapple, and ice cream.

Step 2

Blend - Cover and process on medium speed for about 1 1/2 to 2 1/2 minutes, until thick and smooth. If needed, add more pineapple juice, 1 tablespoon at a time.

Step 3

To Serve - Immediately scoop and add to a cup or bowl. Alternatively, transfer the mixture to a piping bag fitted with a large star tip. Close the end of the bag and freeze for about 30 minutes to firm up but not harden. Trim off the end of the bag and pipe it into the desired serving dish.
