- How to store
- Cool completely, then store in a single layer in an airtight container lined with paper towel, with sheets of paper towel between layers.
- In the fridge
- Up to 3 days at 0–4°C (32–39°F). The shell softens in the fridge; reheat to restore crispness.
- In the freezer
- Up to 1 month in a freezer bag with the air pressed out; freeze in a single layer first, then stack. Texture is best when reheated from frozen in the oven.
- How to reheat
- Reheat in an oven at 180°C (350°F) for 8–10 minutes until hot all the way through (at least 74°C / 165°F in the centre); avoid the microwave, which makes the shell soggy.
- Freezing recommended
- Freezing is possible but not ideal — the plantain shell loses some crispness; fry fresh when you can, and freeze only the shaped, unfried rellenitos if you want to cook them later.
- Signs it has spoiled
- Discard if they smell sour or fermented, feel slimy, or show mould; do not eat rellenitos left at room temperature for more than 2 hours.
