Frying foods with water is not really possible because it does not reach a high enough temperature like cooking oil does.
When you cook foods with water you can only boil or steam the foods and not fry the foods.
To be able to fry foods you need to either use an air fryer or use a deep fryer or pot filled with oil to fry foods.
Oil when heated up during the frying process gets much hotter in temperature than water can so the foods fry and with water it can only boil or steam
The water would also evaporate when it boils or steams so you always need really hot cooking oil to be able to fry or deep fry foods.
