Step 1: Before preparing Isi ewu you have to note that it's difficult to cut up Goat head before cooking so it’s usually cooked first to make it easier for the parts to be torn apart later on and sauced.Goat head is usually very dirty when you buy it so you have to take time to clean it properly. To do this, you get a new razor blade and scrape the outer part of the goat head properly. Then, you slash open the sides of the mouth of the goat head. This makes it easier to pull the jaws apart exposing the tongue and other inner parts of the head. Scrape the tongue also with the blade to remove the remnant meal left behind before the goat was killed. Soak the head in salted hot water for about 20 minutes and wash properly with clean water making sure you focus on the teeth, tongue, ears, and every other part of the head. Use a new iron sponge if necessary. Step 2: Place the washed head in a pot Add some chopped onion, 2 seasoning cubes, and salt to taste. Cook for about 2 hours till it gets soft. Make sure the liquid left in the pot is minimal and concentrated to ensure the seasoning gets into the skull. Once it’s properly done, all you have to do is squeeze the skin off the head and it will come off easily exposing the skull -Set this aside Remove the skin, ears, and tongue from the head, chop into smaller pieces set aside. With a cutlass or hammer, break the skull, remove the brain, and set aside also. it should be whole and intact after being boiled with the skull. You could pound the brain into a smooth paste or chop it into smaller pieces...the choice is yours. Step 3: In a Medium-sized pot/pan, Heat the palm oil till it gets a little bit hot (Not bleached). Gently sieve in the dissolved potash liquid making sure you don't pour in the residue. Ensure there are no lumps in the mixture by stirring thoroughly.
Step 4: Keep stirring till the Oil Turns bright yellow and thickens.
Step 5: Add the ground ehuru, Pepper, Crayfish to the sauce and mix.
Step 6: Gently add the Ugba, pour the cooked goat head chops into the sauce (with the meat stock and brain). Stir Very well and place the pot on the burner and allow the mixture to simmer for about 10 minutes
Step 7: Dish Out into the traditional Isi ewu bowl and garnish with the sliced onion rings and Utazi leaves. Serve as an appetizer with a Chilled drink or a glass of palm wine. Don't be shy to dig in with your bare hands.
