Polenta is a dish which is naturally gluten-free and produced using the best quality certified white and yellow maize available. Moreover, as is the tradition, in order to maintain the authenticity of the product, it is cooked for an hour using a pressure cooker. To reheat the product, just put the entire package of polenta into boiling water, and cook it bain-marie for 10 minutes, or otherwise, open the package, slice the product and heat it on the grill or in the oven (traditional or microwave). The shelf-life of the polenta is one year and it is preservative-free.
