Ingredients:
1) 1 kg of discarded prawn heads and shells
2) 3-4 Cloves of garlic, chopped
3) 1 Onion, chopped
4) Ginger 2-3 slices
5) Salt and White pepper to taste
6) 2-3 tablespoons of fish sauce
7) 2 tablespoons Oil
8) Water 4 cups
9) Chinese Wine 1-2 tablespoons
Heat up oil in a pot and pour in garlic and onion to fried till fragrance. Pour in prawn heads and shells. Fry until slightly brown and fragrant. make sure to bash on the heads with a wooden turner to release all the flavours. Then splash in chinese wine. Pour in water and bring it to boil. Season with fish sauce, sugar (if need be to balance), salt and white pepper.
Simmer for 2 hours until the flavour deepens. Strain off ingredients and keep stock for cooking or storage. I intend to use my stock for my prawn noodle soup.
