For the calypso chicken, place two teaspoons of the pepper sauce in a shallow non-metallic dish with the garlic, paprika, thyme, half the coriander, half a teaspoon of salt and two teaspoons of freshly ground black pepper.
Add the oil and stir until well combined.
Lightly slash each chicken breast and then rub in the pepper mixture until the chicken is well coated.
Arrange the chicken breasts on the grill rack and cook for 8-10 minutes on each side OR until the chicken is cooked all the way through and lightly charred on the outside.
Place the coconut cream and mango pieces in a pan and bring to the boil. Reduce the heat and simmer gently for about five minutes or until the mango is tender.
Add the remaining teaspoon of pepper sauce, one tablespoon of chopped coriander and the lime juice to the mango mixture.
Blend to a purée in a food processor or with a hand blender and season to taste with freshly ground black pepper. Transfer to a bowl.
For the rice and peas, fry the onion in the oil and butter over a medium heat for two minutes then add the garlic and chilli and fry for another two minutes.
Stir in the rice, thyme, and cinnamon stick (if using) until everything is well coated in the oil.
Pour in the kidney beans or peas, add the grated creamed coconut and stir until the coconut has dissolved and the mixture is creamy.
Stir in the hot water with half a teaspoon of salt, bring to the boil, cover and cook over a low heat for 25-30 minutes.
Remove from the heat and set aside, undisturbed, for five minutes. Remove the thyme and cinnamon and discard.
Season the rice and peas to taste with salt and freshly ground black pepper and serve with the chicken.
