Add ¼ c. uncooked brown rice to a blender and process until the rice is ground and cornmeal like in texture. Stir in 2 c. hot water, let soak for 2-4 hours. Add sugar, vanilla and kosher salt and blend until well combined. This will separate as it sits, just pulse or stir it when ready to use. Use immediately or refrigerate.
Make the pudding
In a medium saucepan, measure 2 c. rice milk (you'll have some left) and add 2 c. cooked rice. Cook on medium heat, stirring occasionally, 10 minutes or until hot and thickened. Add extra rice milk if you prefer a looser pudding. Serve warm and top with Unicoi Preserves and your favorite mix ins.
