Start by adding 400 ml of warm water to a bowl, then add the pineapple-flavored gelatin and stir until completely dissolved. Place the heavy cream in a blender and add the dissolved gelatin.

Blend until you get a smooth and homogeneous mixture (about 2 minutes).

Transfer the mixture to a glass dish and refrigerate.

Allow it to set for about 3 hours or until firm. Decorate as desired and serve.
