In a small saucepan, add 1 1/2 cups of the cooked rice (rough measure), and the remaining ingredients starting with 3/4 cup of milk (omit banana if you prefer, see note - and except the zest). Puree the mixture using a handblender (alternatively, you can puree in a blender before adding to the saucepan, but I find the handblender is quicker and easier for clean-up)! Add the remaining 1/2 cup of rice, and turn heat to medium-low. Let the mixture thicken and warm for several minutes. Add the remaining milk if desired to thin. Taste, and adjust with sweetener and orange/lemon zest if desired, and stirring through add-in’s if you like! Serve.
