In a bowl, combine the flour, cornstarch, salt and pepper. Add the eggs and water. Mix well until no more lumps and the batter is smooth.
Heat a pan over medium-low heat and add the cooking oil.
Dip the kamote leaves into the batter and immediately put it in the pan. Fry for 30 secs on each side or until it turns golden brown. Repeat this step on each kamote leaves. Drain the excess oil.
