Boil the potatoes until completely tender. Drain very well and mash while they're hot.
Add the cornstarch, black pepper, salt, and garlic powder. Mix until you have a thick, smooth, moldable dough.
If the dough feels sticky or soft, add another 5-10 g of cornstarch until it is firm enough to hold a shape.
Place the potato dough on a sheet of parchment paper.
Cover the dough with another sheet of parchment paper and use a rolling pin to roll it out into an even rectangle, about 1/4 inch thick.
Remove the top parchment paper and use a sharp knife or pizza cutter to cut the dough into long, even strips.
Gently separate the strips and place them on a parchment-lined tray. Chill the potato strips for 30-40 minutes to firm them up before frying.
Add the mayonnaise, grated garlic, Parmesan, lemon juice, garlic powder, black pepper, salt, and olive oil to a bowl.
Mix until completely smooth and creamy. Taste and adjust the salt, lemon, or garlic according to your preference.
If you want a thinner dipping sauce, mix in 1-2 teaspoons of water.
Heat oil to 350°F (175°C).
Carefully place the chilled potato strips into the hot oil. Do not overcrowd the pan or move them for the first 60 seconds, allowing the outside to set.
Fry for 3-4 minutes, turning gently, until golden brown and crisp.
Remove and drain on a wire rack or paper towels.
Garnish with freshly grated Parmesan cheese and parsley. Serve warm and enjoy.

If the potato dough is too sticky, gradually add more cornstarch until it reaches the desired consistency.
For extra crispiness, ensure the oil is at the correct temperature before frying.
Can I use a different type of potato?
Russet potatoes are recommended for their starch content, but you can experiment with other types if desired.
How do I store leftovers?
Store leftover fries in an airtight container in the refrigerator for up to 2 days. Reheat in the oven for best results.
Can I bake the fries instead of frying?
Yes, you can bake them at 400°F (200°C) until golden and crispy, though they may not be as crispy as fried.
What can I substitute for avocado oil?
You can use any high smoke point oil like canola or vegetable oil for frying.
How can I make the mayonnaise spicier?
Add a pinch of cayenne pepper or a few drops of hot sauce to the mayonnaise for extra heat.
