Chef Tips from the Video

Troubleshooting

Storage

Refrigerator: Store leftover fries in an airtight container for up to 2 days; reheat in a hot oven (425°F) to regain crispness.

Freezer: Cool fries completely, then spread on a tray and freeze. Transfer to a freezer bag; reheat from frozen in a preheated oven for 12‑15 minutes.

Room temperature: Do not leave fries at room temperature for more than 1 hour as they will become soggy.

Make-Ahead Tips

• Slice and soak potatoes up to 24 hours in advance; keep them refrigerated in water.
• Prepare the garlic truffle aioli a few hours ahead and store covered in the fridge.
• Reheat leftover fries in a preheated oven at 425°F for 8‑10 minutes to restore crispness.
