Nyonya laksa is synonymous with laksa in Singapore. Most Singaporeans are familiar with Nyonya laksa and many know the history of the spicy noodle soup dish. But, to the bigger question of where do laksa come from - that's a harder one to answer.
When you ask Singaporeans about laksa, most will immediately think of Nyonya or Peranakan laksa. It is the Malay - Chinese fusion curry laksa attributed to Peranakan (Malay for "local born"), exemplified by Katong laksa. Katong laksa has an interesting history.
