Wash and clean chicken feet, then add chicken feet to an instant pot or traditional pressure cooker.
If using an instant pot add 5 cups of water to the pot and 1/2 teaspoon of salt, 1 tablespoon of garlic powder, 1 tablespoon of onion powder and a pinch of black pepper
If using a traditional pressure cooker, add enough water to cover the chicken feet, then season as listed in the step above
Pressure cook on high for 30 minutes with the instant pot or until the chicken feet are tender and the skin is almost pulling off the bones
While the chicken feet are pressure cooking, warm the oil in a large stock pot on medium-high heat Then add the onions and garlic and sauté until the onions become soft and translucent, for about 5 minutes
Next, add the pumpkin to the stock pot followed by salt and a pinch of black pepper
Cook until the pumpkin is soft and mushy, then add the white sweet potatoes, diced plantains and regular sweet potatoes.
Add the parsley flakes or fresh parsley and wiri wiri pepper and mix together well
While you are waiting for the chicken feet to finish pressure cooking add 5 cups of water to the stock pot and turn the heat down to low and allow everything to cook in a low simmer.
When the chicken feet are done pressure cooking, release the pressure according to instructions in the instant pot manual, then pour the chicken feet and broth into the stock pot
Mix together, then increase the heat to high heat and continue to cook the soup until the sweet potatoes and plantain are tender
Using the back of your pot spoon, crush some (about 1/4) of the sweet potatoes and mix into the broth of the soup, then mix together well to form a smooth velvety broth
Serve warm
