Poblano and Cheese Tamales (Tamales de Rajas con Queso)
In Mexico, people use Chihuahua cheese or Oaxaca cheese for these tamales. If you can find them, use them!
When boiling the tomatillos make sure that they don't break open, otherwise they get very bitter.
You can also cook tamales in a pressure cooker. Then the cooking time will only be 30 minutes.
