What is the best set of pots for those who cook every day?

Get some cast-iron cookware of high quality. You ought at least to have a small skill, a large skillet, a Dutch oven. (Mine’s made by Lodge) Get a cup of stainless steel, too. You may also want to make pancakes, omelettes and grilled cheese sandwiches using a non-adhesive frying pot, although all of them can be made with cast iron. This should cover most cooking requirements. Good luck!
