In a frying pan, add the blended ingredients and lemongrass and saute for 10 minutes.
Add coconut milk, salt, coconut sugar and tamarind juice and continue cooking for another 10 minutes.
Add the chicken, mix well and cover till the chicken is cooked for about 20-25 minutes.
Once the chicken is cooked, remove the chicken from the sauce and continue cooking the sauce till it thickens.
You can skewer the chicken through some satay sticks if you prefer. This is an optional step though.
Lightly brush a grill pan with some oil and grill the chicken. Keep basting the chicken with the reduced sauce.
The chicken is ready once it is slightly charred.
