Skillet Grapefruit Upside-Down Cake

Drink it or eat it, but get some Vitamin C however you can! Citrusy, not too sweet, and with a slight crunch from the cornmeal, this moist cake takes advantage of our favorite sweet red grapefruits, Texas Rio Star. Plus, the sunny color is sure to be uplifting in these dark days of winter.
