All ingredients ready? Let's begin!
In a large stockpot over medium heat, warm the olive oil or ghee. Add the shallot, carrots, celery, fennel, and sweet potato. Sauté the vegetables for 5 minutes, stirring often.
Add the thyme and bay leaf, and continue to sauté until the vegetables start to turn golden and the herbs are fragrant. This should take about 3 to 5 more minutes. Again, stir so the vegetables don’t stick to the pot or start to blacken. Turn the heat down if needed.
Add the broth and saffron to the pot and turn the heat to high. As soon as the broth comes to a boil, reduce the heat to a rolling simmer. Cook until the potatoes are almost softened, about 5 minutes. Season with salt and pepper to taste.
Remove the bay leaf from the soup. Stir the cream of the coconut milk into the coconut water to make a smooth milk. Add the coconut milk, fish, and shrimp to the pot. Cook for another 3 to 5 minutes or until the fish and shrimp are just opaque.
Ladle the hot soup into individual serving bowls.
Garnish with parsley and serve while hot with AIP-compliant cassava chips, biscuits, or crackers.
