Cinnamon to taste (optional)
Stevia to taste
Take a knife around the inside peel of the grapefruit so that it cuts out the grapefruit from the peel. (I usually have to use my fingers after this to pull the grapefruit out.) Separate the sections and place in a bowl. (It's best if the grapefruit is really juicy. If it's not, sprinkle with a bit of water to moisten.) Sprinkle with Stevia and cinnamon. Toss, then place back into grapefruit peel. Broil for about 3-5 minutes until caramelized.
