Once the beef is done, remove the meat into a bowl and set aside. Put the dutch oven over medium high heat and reduce by about half.
While that reduces, heat another large dutch oven (with a lid) on the stove top on medium heat. Add the coconut oil and curry paste and stir fry until fragrant. Add 1/2 can of coconut cream (or coconut milk) and mix to combine. Simmer, stirring frequently, until the mixture bubbles red.
Add the reduced cooking liquid from the beef, the remaining coconut milk, the braised beef, potatoes, and carrots, and kaffir lime leaves to the pot. Bring to a boil, cover and reduce the temp to medium and simmer for 30 minutes.
Add the fish sauce, sugar, tamarind liquid and peanuts and cook for another 15 minutes. Taste the liquid - if too salty, add water 1/4 cup at a time.
