Marinate the Chicken with salt, cumin, garlic, oregano, chilli powder, oil and lime juice and keep aside preferably overnight but 30 - 60 mins will do
Blend all the sauce ingredients together to a smooth paste
In a saute pan add the Chicken and sear on both sides for some great color, remove and keep aside to cool, it’s ok if the chicken is not fully cooked
In the same pan add the sauce and bring to the boil
Cut the chicken pieces into smaller chunks and add back in
Add the water to the food processor so you don’t waste any of that sauce and add it in
Finally finish off with the heavy cream and serve with rice
