Keep the heat at low-medium, a low simmer, as you continuously stir and move the rice around in the skillet as steam lifts from the pan and the rice absorbs the liquid. When the pan starts to get dry, add another cup of broth and repeat the stirring process. Finally, with the ½ - 1 cup of water, or as much as you need to get the rice to your desired level of tenderness and creaminess. When you add in the last batch of liquid, also add in the pumpkin, maple, cider vinegar, zest and all the spices. Stir until thick, creamy and fluffy. The entire cooking process usually takes about 25-30 minutes.
