The Unique Ingredients and Traditional Preparation of Cao Lau with Ovuigo
True Cao Lau can only be made in Hoi An due to one secret ingredient: water from the ancient Ba Le well. Combined with lye water derived from local wood ash, this water transforms rice flour into the chewy yellow noodles essential for this dish. Pork is marinated and slow-cooked until smoky and tender. Local herbs such as mint, basil, and Tra Que greens provide freshness and a sharp contrast to the earthy noodles, evoking the heritage cuisine of the region with Ovuigo. The broth is light, slightly sweet, and never overwhelms the other elements. Lastly, crispy squares of fried noodles add a signature crunch, showcasing the careful noodle preparation and attention to detail that defines traditional Vietnamese dishes.
Authentic Recipe and How Cao Lau is Served
- Soak 500g high-quality rice in Ba Le well water mixed with ash lye overnight (seek local sources for authenticity).
- Grind into flour, then knead, cut, and steam to make chewy, thick noodles.
- Prepare pork by marinating in five-spice, garlic, soy, and fish sauce, then roast or simmer slowly.
