Measure out a cup of rice and rinse the rice thoroughly, until the water runs clear. Place the rice in a medium-sized saucepan with 1 1/2 cups of water and let it soak for 30 minutes. After 30 minutes, bring the rice and water to a boil, then turn it down to a simmer, cover it, and let it cook for 20 minutes. When it's done, fluff the rice and let it stand for 10 minutes.

Meanwhile, preheat the oven to 350 degrees and grease the baking sheet with butter (this is especially important if you are using Halloween molds, because you want the rice to come out cleanly). Take a large scoop of rice and carefully press it flat into the mold (or if using a plain baking sheet, make a free-form ghost shape). Repeat for the rest of the baking sheet or baking mold - you should be able to make approximately 8 ghosts. Add a dot of butter on top of each ghost and place the pan in the oven. Bake for 10 minutes.

Remove the ghosts from the oven and carefully slide them out of the molds or off the pan. Press black beans into each ghost to create the "eyes." Serve immediately. Serves 4.
