Add the beef pieces to a large bowl then add the 2 tablespoon of curry followed by the beef seasoning, black pepper, pink salt, garlic, scallion, onions, bell peppers, ginger.
Use your hands to work all of the ingredients into the beef until it is completely coated .
Set aside and refrigerate overnight
On medium heat, melt the olive oil and sprinkle in the 1 teaspoon of curry powder then cook the curry for about one minute.
Then toss the bowl of beef into the pan/skillet and proceed to brown the meat
This should take up to 10 minutes, stirring so each side is evenly browned. The beef should form it's own juices during this time (try to cook of most of the juices as this will optimise the flavour).
Once seared add the browned beef to your slow cooker.
Add the potato pieces (if you are adding them now) and sprigs on thyme, coconut cream and tomato paste in the crock pot.
Finally pour in the 2 cups of warm water and stir.
Adjust the setting to high and timer for 4 hours.
Add the sweet potato 1 hr-45 minutes prior to the finishing time, if you are adding them now.
30 minutes before serving, prepare your slurry to thicken the sauce by mixing the tapioca starch with the cold water into a smooth albeit runny paste.
Add the slurry to the crock pot, carefully mixing so that it is evenly distributed.
Do a taste test and adjust seasoning if required.
Serve accordingly
