Peel, devein, and rinse shrimp with lime or lemon juice and cool water. Drain well, then season with 1 tablespoon olive oil, 1 tablespoon green seasoning, ⅓ of the salt, ⅓ of the black pepper, and ½ tablespoon curry powder. Set aside.
Heat a deep pot over medium heat and add the shrimp. Cook for 2–3 minutes until just done, then remove and set aside.
In the same pot, add remaining olive oil, onion, garlic, and anchar masala. Cook on low for 3 minutes, then stir in the remaining black pepper, 1 tablespoon of green seasoning, and the rest of the curry powder. Cook until fragrant and the spices bloom.
Add bodi and stir to coat with the spice base.
Add coconut cream, Scotch Bonnet (if using), remaining salt, sliced potato, diced tomato, and water. Stir well to combine.
Bring to a boil, then reduce heat to a simmer. Cook for 25–30 minutes, stirring occasionally and adding water if necessary, until vegetables are tender.
Once the vegetables are done, return the shrimp to the pot, stir gently, remove from the heat, and let residual warmth finish cooking the shrimp. Serve hot.
At this point, everything should be tender. Add the shrimp we cooked earlier, stir well, shut off the stove, and you’re done.
