Cut sweet potatoes in thin strips. If they're not cut in long, thin strips then they're not really "French" fries. But since I wanted to arrange the fries in the shape of the sun, I cut some in circular shapes as well.
Heat oil in a kadai (wok) on medium-high heat. I used an iron kadai and filled it halfway with oil.
To test whether the temperature of the oil is right for frying, place a wooden spatula or spoon in the oil. Bubbles should form and float up towards the surface.
Fry for 3-4 minutes, you'll be able to tell when to take them out by their color—not too white, not too brown.
Remove the fries from oil and place them on paper tissues so that excess oil is absorbed, and then sprinkle some salt on them.
If you are making these fries for older kids, you can also sprinkle some pepper powder.
You can serve with tomato ketchup or salsa sauce. Although, they taste great even without any accompaniment.
