In a dry pan over medium heat, roast 1 Tbsp korerima for about 2 minutes until it toasts and becomes fragrant. Place the toasted whole spices into a spice grinder and grind them into a powder.
Add 1 lb unsalted butter to a large pot on the stove and put it over medium heat, allowing the butter to melt. Once the butter melts, add 2 tsp of the ground korerima and the remainder of the spices and aromatics (2 Tbsp koseret, 1 Tbsp besobela, ¼ tsp ground turmeric, 1 Tbsp freshly minced garlic, and 1 Tbsp freshly minced ginger).
Cook over low heat, allowing the butter to bubble. A foam will start to form on top of the butter, and the bubbles will get stronger. Continue stirring during this process to release steam so that the bubbles do not spill over the top of the pot.
Cook in total for about 20-30 minutes or so, until you see the milk solids settle at the bottom of the pot.
You will know your niter kibbeh is done when most of the bubbles calm down and the film is mostly gone from the top of the butter. There may still be some white residue on the top of the butter, but most of it will be gone. There will also be a bit of a toasty brown color to the milk solids at this point. See photos above for visual cues.
At this point your ghee has finished cooking, so line a mesh strainer with a cheesecloth and place this on top of a glass bowl. Ladle the niter kibbeh into the mesh strainer so that only the clear ghee is left over and all of the spices are removed.
Place in a jar where it will harden. Enjoy!
