Arrange the hen halves in a baking dish. Combine all the ingredients except the sesame seeds in a bowl to make a paste. Smear the past all over the hens. It's a satisfying experience. Make sure to get the paste in all the nooks and crannies. Cover with saran wrap and let sit out for about an hour.
After an hour (or two), preheat the oven to 375. Remove the saran wrap, sprinkle the hens with sesame seeds, place in the center of the oven, and bake for about 30-45 minutes. Remove and let the hens rest for 5 minutes or so. Serve and enjoy!
