Ingredients
  

For the Fries:
  • 3 large potatoes (Sebago, Coliban, Golden Delight, or Kennebec)
  • 8 cups vegetable oil (for frying)
  • Sea salt (to taste)
For the Mayonnaise:
  • 1/4 cup mayonnaise (the star condiment)
  • 1-2 egg yolks (at room temperature)
  • 1 tsp mustard (for flavor)
  • 1 tsp white vinegar (for tanginess)
  • 1 cup neutral flavored oil (such as sunflower, grapeseed, or canola)
  • Salt (to taste for mayonnaise)
  • 1 bulb garlic (whole, optional)

Equipment

  • Large heavy-bottomed pot or deep fryer
  • Slotted spoon or spider
  • Knife and cutting board
  • Mixing bowl
  • Whisk or immersion blender
  • Paper towels

Method
 

Preparation Steps
  1. Begin by washing and peeling the potatoes. Cut them into thick slices, about 1/4 to 1/2 inch wide. Rinse under cold water, then pat dry with paper towels.
  2. Heat the vegetable oil in a large pot to 320°F (160°C). Use a thermometer for accuracy.
  3. Add the cut potatoes to the hot oil in batches. Fry for about 5 minutes until soft but not browned. Drain on paper towels and cool for 30 minutes.
  4. Increase the oil temperature to 375°F (190°C). Fry the blanched fries in batches until golden brown and crispy, about 3-4 minutes. Drain on paper towels and season with salt.
  5. In a mixing bowl, combine egg yolks, mustard, and vinegar. Whisk together, then slowly drizzle in neutral oil while whisking to emulsify. Season with salt to taste.

Notes

  • For extra flavor, consider adding roasted garlic to the mayonnaise.
  • Leftover fries can be stored in an airtight container in the refrigerator for up to 2 days.
  • Double fry the potatoes for extra crispiness just before serving.
