Wash the oxtail as instructed (see above).
Place the oxtail in a large bowl.
Add the beef seasoning, paprika, onion/garlic granules, black pepper, soy(a) sauce, browning, onion, scallion and garlic.
Use your hands to rub the marinade into the meat.
Wrap the bowl with cling film/saran wrap, refrigerate overnight or for at least 3 hours.
Add olive oil to a large skillet/frying pan on medium heat, scrape off the onion, scallion and garlic and brown the oxtail alone. This should take roughly 10-15 minutes.
Add the onion, scallion and garlic from the bowl to the skillet/dutch oven and saute until soft.
Now, stir in the tomato paste, carrot, thyme and dried butter beans (if you are using them).
Pour 4 cups beef stock/water in the dutch oven/skillet.
Start with 4 cups and add more water, if needed, during cooking time.
Reduce the pot to low heat, cover with lid and cook for up to 4 hours. (If you are using canned beans, add them 45-30 minutes before finishing.)
For a thicker stew, mix the starch/water together and stir in the slurry 45-30 minutes before finishing (this is optional).
Do a taste test and add black pepper and pink salt, if needed.
