The potatoes absorb the good taste of chicken really well. It goes well with rice, so have plenty of rice with this.
When I boiled potatoes, I cooked chicken at the same time in the same pan. The potatoes absorbed the good flavour of chicken, so I just seasoned it to make it go well with rice.
At the ③: 5 minutes after adding the seasonings check the potatoes with a skewer. Cook the potatoes until a skewer goes easily.
