Pre-cooked. Ready to heat serve. Fat free/gluten free. History of Polenta: In Italy, Polenta is a versatile alternative to pasta, bread or rice, and is especially suited for meat dishes that have plenty of sauce. In northern Italy, it's as popular as pasta is in the south. Traditionally, the first cooking step required stirring for 40-45 minutes in a copper kettle over a hot fire. Pre-cooked Polenta eliminates this tedious chore, while preserving Polenta's ancient Italian heritage. There may be some water separation, this is normal.
