Start by placing the potatoes chopped into sticks into a large skillet over medium heat filled with boiling water and let them cook for 5 minutes.
After this time has passed, drain all the water and transfer the potatoes to a large bowl.
Add enough cold water to cover everything and add a few ice cubes.
Stir and let them soak for 10 minutes.
Next, remove the potatoes from the water and dry them thoroughly with paper towels.
Transfer them to a large bowl, add the cornstarch and mix everything thoroughly to combine.
In a large skillet over medium to low heat, add the vegetable oil and let it heat up.
Add the potatoes we prepared one by one to prevent them from sticking and fry them until golden brown.
Remove them from the skillet and transfer them to a plate lined with paper towels to drain the excess oil.
Next, transfer them to a large bowl, season them with the salt, the black pepper, the sweet paprika and mix everything very well.
Serve.
