The simple answer is that any type of pot can be used as long as it heats evenly. To follow the tradition of making risotto, a person should use a copper pot, but an aluminum or steel pot works just as well. The shape of the pot should never be a high-sided, narrow pan because it will cause the risotto to not cook evenly. It is common for a two-handed pot to be used due to the height of it, but a one-handled pot can be used as long as it is about 6 centimeters.
