•    8 cloves garlic (crushed)
•    3 Tbs crushed red Chillies
•    5-6 cardamoms

•    1-2 pieces Rampe (Pandanus leaves)
•    1 piece Sera (Lemongrass)
•    1 piece Cinnamon
•    Salt to taste
•    1 tsp Tamarind paste
•    2 Tbs Sugar
•    4-6 Tbs Vegetable oil
METHOD: Mix the first 12 ingredients well. Heat the oil in a shallow pan. Add the mixed onions and keep stirring. When the onions are well fried and dry, add the tamarind paste and keep stirring until well mixed. Allow to fry a few minutes longer. The mix will turn dark brown when well fried.
