Make sure you know how long tamales take to cook on the stove, in a Dutch Oven, a regular pot or even a pressure cooker!
Cooking tamales in a steamer or tamalera pot is the most traditional way. Read the article for the details.
If you don't have a tamalera steamer pot you can use a regular large pot with a steamer basket.
Another of my favorite way to cook tamales is in a pressure cooker. It cuts down the time by a lot!
