Chop one small apple into bite-size pieces.
Add the crushed pineapple, whole cranberry sauce and chopped apple to a bowl.
Mix them together.
In a separate bowl add 2 packs of strawberry gelatin.
Add 1 ¾ cups of boiling water to the gelatin powder. Whisk for two minutes to fully dissolve.
Pour the liquid overtop of the fruit and stir together. Place in the fridge for 3-4 hours to chill and set.
Once fully chilled, stir with a spoon to break up the gelatin. Keep in the fridge until ready to serve.
