In a medium saucepan, bring broth to boiling. In a very thin stream, slowly add cornmeal to the boiling water (keep the broth always at a boil), whisking constantly. Using a wooden spoon, cook and stir until mixture returns to boiling, scraping sides of saucepan. Reduce heat to low. Continue to cook and stir for 5 minutes or until mixture is soft, very thick and the mixture pulls cleanly away from the sides of the pan. Remove from the heat.
