Preheat oven on 400°F. If you have a roast setting, use it.
Working directly on a sheet pan, combine the brown sugar and spices. Add the oil and the lime juice. Mix to combine, then add the corn riblets. Toss it all together making sure that the riblets are coated well.
Bake uncovered for about 35-40 minutes, mixing once in the middle.
You might want them to char a bit more (the crunchy bits are the best part) so keep an eye and bake them to your liking.
Serve with lime wedges and season with lime juice. Serve immediately.
