Notes
My Top Tips♡ Be sure to drain the canned pineapple and mandarin oranges well or the gelatin won't set firmly.♡ Don't use fresh pineapple. It contains an enzyme called bromelain that prevents gelatin from setting. However, heat destroys the enzyme, which is why canned pineapple can be used.Make-Ahead & StorageMake-Ahead: For the best results, make this Jello salad the day or night before serving, so the gelatin has time to set firmly.Storage: Leftovers can be kept in the refrigerator covered in plastic wrap or stored in an airtight container for up to 1 week. You can transfer the salad to a smaller container to save space in the refrigerator.
