1. How long it takes to cook potatoes depends on the size and amount of potatoes. Of course, it also depends on what kind of pot you use, whether you use an induction cooker or a gas stove. If you use a regular pot to cook a plate of small potato cubes, it will take about three to five minutes to cook over high heat.

2. If you use an ordinary pot to cook four or five medium-sized dishes, it will take fifteen to twenty minutes. If you are using gas, boil it over high heat first and then reduce it to low heat. However, it is best to prick it with chopsticks halfway through to confirm whether the potatoes are soft and cooked through.
