2 tsp black peppercorns
5-6 large cloves garlic, coarsely chopped
3 tbsp coarsely chopped coriander roots
pinch of salt
1 tsp fish sauce
Place the peppercorns in a mortar with the garlic and pound to a paste. Add the coriander roots and salt. Pound to a smooth paste. If you have a small blender/mini food processor you can use that instead. Stir in fish sauce.
