Method
1. Saute pounded ingredients until aromatic, followed by lemon grass. 
2. Add Tauchu, and continue to cook for a minute or two.
3. Toss pork into pan and brown it for six to ten minutes.
4. Add chilies.
5. Fill pan with tamarind juice, salt and sugar to taste, and simmer for one and a half hours.
6. Serve hot with white rice.
