The Exquisite "Liquid" Essence:

The sauce, with its glossy, thick brown hue, is meticulously crafted from duck broth, combined with signature spices like fragrant fried shallots and garlic, fish sauce, chili, vinegar, sugar, and ginger. Tapioca starch is added to achieve the perfect velvety consistency. The tangy sourness of vinegar, the subtle sweetness of sugar, and the spicy kick of chili all harmonize to create an addictive sauce, truly unique and unforgettable.
• Flavorful Broth (Nước dùng đậm đà): A separate bowl of hot broth, simmered from duck bones or duck broth, seasoned to perfection, is often served alongside. This allows diners to sip and savor the rich broth, balancing the palate.
