You can apply this recipe to any type of curry you like. If you like your food really spicy, try adding dried chili flakes or whole fresh chilies. Curry is a simple, hearty dish; get as creative as you want! As always, practice makes perfect.
In a medium saucepan, heat 4 tablespoons of the thick coconut cream on high for about 1 minute, then add the oil. When the cream starts to sizzle, stir the curry paste into the cream like building a roux. Stir-fry the paste for about 1 minute, until the paste starts to thicken, dry out and become fragrant. If the curry starts to sputter, add a small amount of coconut milk and/or oil to keep the paste moving. Cook the paste until it has the consistency of peanut butter.
Stir the sweet potato cubes, onion, basil, half of the lime leaves and remaining coconut milk into the curry paste. Increase the heat to high until you reach a full rolling boil, then reduce to a simmer. Let the curry simmer for 10 to 15 minutes or until the potatoes are fork-tender. Also check that the curry is thick enough to coat the back of a wooden spoon.
Add the chicken. Let this simmer for 5 to 7 more minutes, or until the chicken is cooked through. Stir in the fish sauce, sugar and tamarind. Add the bell pepper strips and turn off the heat. Serve hot over cooked rice. Garnish with the Thai basil, remaining lime leaves and diced bell pepper.
