Preparing the Goat Head (Approx. 1 hour 30 minutes)
Cook the Goat Head: Place the Goat Head (thoroughly washed, including the tongue) into the large cooking pot. Add the chopped onion, 2 Seasoning Cubes, and a pinch of Salt. Pour in enough Water to cover the meat.
Bring to a boil, then reduce heat, cover, and let it cook for about 1.5 hours (90 minutes), or until the meat is tender and easily separates from the bone. If using the Goat Brain, either cook it wrapped in foil alongside the head or simply toss it in to cook with the meat.
Blend Crayfish: While the goat head cooks, blend the 1/4 cup of Crayfish and set aside.
Creating the Sauce Base (Approx. 5 minutes)
Blend Abacha: In a blender or food processor, combine the 1/2 cup of Abacha (shredded dry cassava) with the 1/2 cup of Hot Boiled Water. Blend until it forms a smooth, thick paste. This paste replaces the traditional potash/akwu mixture for thickening.
Prepare the Pepper Mix: Use a mortar and pestle or a small blender to pound or blend the 2-4 Scotch Bonnet Pepper pieces and 1 tablespoon of Ogiri (if using) into a rough paste.
Separate and Chop Meat: Once the goat head is tender, remove the meat pieces from the pot (reserve the stock!). Separate the meat from the bone and chop it into smaller, bite-sized pieces.
Mixing It All Together (Approx. 5 minutes)
Combine Ingredients: In a clean pot (or the pot used for boiling, drained of stock), add the blended Abacha paste.
Add Palm Oil: Pour in the 1/4 cup of Palm Oil and stir vigorously with a wooden spoon until the mixture is uniform and the oil is fully incorporated.
Add Seasonings: Mix in the pounded pepper mix (Scotch Bonnet and Ogiri), the blended crayfish, the 1 teaspoon of blended Ehuru seeds, and the sliced Uziza Leaves (or Kutaisi, if using). Season with Salt to taste.
Add Goat Head: Finally, fold in the cooked and chopped Goat Head pieces. Ensure every piece is well coated with the vibrant, spicy sauce.
Final Cooking and Serving (Approx. 8-10 minutes)
Steam: Transfer the pot to the stove and let it steam for about 6 to 8 minutes on low heat. This low-temperature cooking allows the rich flavors to fully meld into the meat. Do not let it boil excessively.
Serving the Dish: Once cooked, your Isiewu is ready! Serve immediately while hot. Garnish with fresh Onion Rings and the traditional Utazi leaves or the alternative Baby Spinach or parsley.
