Caramelize the Sugar: In a heavy-bottomed 5-quart pot, heat the brown sugar over high heat until it froths, bubbles, and darkens. This step creates the characteristic smoky sweetness of pelau.

Cook the Mushrooms, Peas, and Rice: Add the chopped king oyster mushrooms, pigeon peas, and rinsed rice to the pot. Stir well, allowing the mixture to cook for 3 minutes, absorbing the caramelized sugar flavor.

Add Vegetables and Seasonings: Mix in the cubed carrot, red bell pepper, pumpkin, celery, onion, and green seasoning. Season with salt and black pepper.

Simmer with Coconut Milk: Pour in the coconut milk and water, ensuring the mixture is covered by at least an inch of liquid. Bring to a boil, then reduce heat to low and cover the pot. Let it simmer for 30 minutes or until the rice is fully cooked and the liquid has evaporated.

Final Taste and Serve: Once cooked, fluff the rice with a fork and adjust seasoning if necessary. Serve hot with fried plantains, coleslaw, or a green salad for a complete meal.
