STEP 1 For the filling, soak noodles in warm water for 5 minutes to soften. Drain, then use scissors or a knife to cut noodles into short lengths. Use a mortar and pestle to pound the garlic, peppercorns and coriander root to a fine paste. Heat vegetable oil in a pan over medium heat. Add the garlic paste and cook for about a minute. Add the pork and cook until just cooked through. Then add the noodles, carrot, cabbage and fish sauce. Cook for about 3 minutes or until vegetables have softened. Taste and season with more fish sauce if needed. Set aside to cool completely.
STEP 2 Make the spring roll glue, by mixing the flour and water together to form a thick paste.
STEP 3 Place about a heaped tablespoon of filling onto a wrapper. Fold like an envelope and roll up, sealing with the spring roll glue. Repeat with remaining filling and wrappers.
STEP 4 Heat enough vegetable oil in a saucepan for deep frying. When the oil is hot, cook spring rolls in batches for 3-4 minutes or until golden brown. Remove and drain. Serve with the dipping sauce.
