Light the pit. If you're using wood, it will look like this.
Wait until the wood has started burning low like this. It's still very hoy so make sure you use all the water
In the cast iron pot add milk, water, salt and polenta and stir until all mixed in
Cover but keep on stirring consistently. The fire can't be controlled like a stove so you need to check on it as often as possible. Add more water while tasting if it's cooked
When it reaches this consistency, it is ready to be removed. Please use protective clothing because the pot will be extremely hot. Serve when ready while it's hot.
