1. 1
   Peel the sweet potatoes, inspect them, and trim a small piece to create a stable base. Cut them into half-centimeter-thick slices, then cut those slices into fries.

2. 2
   Place the cut sweet potato fries into a large container.
   ▶ ≈0:39
3. 3
   In a bowl, whisk together 2 tablespoons of all-purpose flour.
   ▶ ≈0:39
4. 4
   Add 2 tablespoons of cornstarch, ¼ teaspoon of baking powder, and ¼ teaspoon of baking soda. Mix well. The baking powder and baking soda create a light and crispy texture.
   ▶ ≈0:48
5. 5
   In another bowl, mix 1 tablespoon of white vinegar with 1 tablespoon of water. The vinegar prevents browning and helps make the fries crispier.
   ▶ ≈1:03
6. 6
   Layer the flour mixture and vinegar-water solution onto the fries in three batches. First, add one-third of the flour mixture and toss to coat.
   ▶ ≈1:16
7. 7
   Add half of the vinegar-water mixture and toss to combine.
   ▶ ≈1:22
8. 8
   Add the remaining half of the flour mixture, then the remaining half of the vinegar-water. Toss everything together.
   ▶ ≈1:28
9. 9
   Finally, add the last portion of the flour mixture. Layering the coating this way creates a thicker, crispier crust.
   ▶ ≈1:35
10. 10
    Deep-fry the fries in oil heated to 320°C (608°F). Fry in two batches to maintain the oil temperature.
    ▶ ≈1:48
11. 11
    Separate the fries to prevent sticking. Fry for about 4 minutes over medium heat, stirring occasionally.
    ▶ ≈1:55
12. 12
    Remove the fries from the oil. Season with salt. Optionally add black pepper, parsley, paprika, cumin, or chili powder to taste.
