Sweet Potato Fries and Spicy Mayo

For the Spicy Mayo:

In a blender, combine all ingredients and process until smooth. Taste and adjust seasoning as needed. Store covered in the refrigerator until ready to use.

For the Fries:

Heat oven to 200 degrees F. In a large cast iron skillet, pan, or Dutch oven, heat vegetable oil over medium-high heat to 350 degrees F.

Meanwhile, peel sweet potatoes and cut lengthwise into ½-inch planks. Cut planks lengthwise into ½-inch strips. Place strips in hot water with vinegar while oil finishes heating. Line a plate with paper towels and set aside.

When oil is heated, drain fries and thoroughly pat dry with paper towels. Add ⅓ of the fries to oil and cook until browned and cooked through, about 4 to 5 minutes. Remove fries to paper towels with a slotted spoon and season immediately with kosher salt. Return oil to 350 degrees F and repeat with remaining fries. Hold in oven until ready to serve.
