Use Regular or Ruby Red Grapefruit(I love Ruby Red)
Recipe
Turn the oven on Broil. Cut the Grapefruit in Half. One each half sprinkle some Cinnamon, nutmeg, and sweetner. Then place the halves on a tin or foil pan, put them in the oven. Wait about 1-2 mins..... Once the Cinnamon is bubbly, it is ready.
