The Modern Nonna

0 Preheat the oven to 425F (220C).
1 Take a whole pineapple and cut off each end.
2 Place it flat-side down. Now, with a sharp knife, start cutting the outer skin, starting from the top and gliding the knife all the way to the bottom. You are going to cut off all the skin around the pineapple.
3 If there are any remaining harder brown bits, remove them with a knife or pointed end of a potato peeler.
4 In a separate plate, mix together brown sugar and cinnamon. Roll the pineapple in the cinnamon sugar mixture or use your hands to press it on.
5 Take the oven vertical spit and stick the pineapple onto the skewer by piercing it through the center of the core.
6 To prevent the sugar from burning while cooking, add some water to the bottom of the plate. Alternatively, you can also try using pineapple juice instead of water (although I have not personally tried this). Make sure to keep an eye on the liquid and add more as needed to prevent the bottom of the plate from burning. Please note that I have not personally tried using pineapple juice in this way.
7 Place the pineapple in the oven and bake for 45-60 minutes. I like to put mine on broil (top burner only) for the last 5 minutes to char the top, but keep a very close eye on it.
8 Once cooked, make vertical slices and enjoy!
9 Note: I used the smallest skewer out of the three that came with the vertical spit.
