Blend two onions, tomatoes, pepper and turkey berries together, set aside. Remove the flesh of the salmon, break into two and remove the bones, break into desired sizes, set aside. Wash the soaked melon seeds and put into a blender. Add about ¼ teaspoon salt and just enough water to blend into a paste. Set aside. Slice the remaining onion.
Pour palm oil into a medium saucepan, add half of the sliced onions and momoni if using. Fry till onions are softened. Add the blended tomatoes, onions, turkey berries and pepper. Bring to a simmer on medium heat. Add the salmon, salt and grounded shrimp if using. Cover and let simmer for 7 to 10 minutes till sauce is bare thickened.
Add in the blended melon seeds, DO NOT STIR, cover and reduce heat to low. Let it simmer 8 to 10 minutes or till the blended melon seeds sets. Gently stir in the steamed kontomire. Add the remaining sliced onions, let simmer for about five minutes till onions are softened. Serve with yam, rice, cocoyam, cassava, plantains or sweet potatoes.
Spinach can be substituted for kontomire. Do not steam like we do for kontomire leaves, cut it up and add it up after the blended melon seeds set. Leave to simmer till it is softened and cooked through. You can also substitute equal amounts of already grounded melon seeds (akatoa/agushie). Season with salt, make a slightly thick solution with water and add in.
