Are you familiar with the campfire treat of a cupcake baked in an orange? I've never actually tried it, but it popped into my mind as I continued to think up uses for the oranges from our extremely prolific tree. I thought it would be fun to try, though we have no camping plans in the near future and building a campfire in our backyard would be inappropriate. I vaguely recalled reading that you could make them on a backyard grill. I checked Cupcake Project for a recipe - success!
At the end of the recipe, there was a brief note that you could bake them in an oven. Well, that sounded even more appealing than firing up the grill. The recipe was for a vanilla cupcake, but I decided that I'd make chocolate. I like orange with chocolate, plus it seemed more creative than actually following a recipe. (Savvy readers will note the use of foreshadowing.)
I began by choosing three huge oranges. (Imagine grapefruits instead of oranges. That size.) I washed them, cut off the top third or so, then removed the pulp using the Avocado Cutter, which worked very well.
