Phở Chua Lạng Sơn

1. Overview

Phở chua (sour pho) is a refreshing and flavorful noodle dish that originates from Lạng Sơn Province, in Vietnam’s northeast. Unlike the classic hot pho with beef broth, this version is served cold or at room temperature, with a sweet-sour sauce, a variety of toppings, and a harmonious balance of textures and tastes.

Phở chua reflects the culinary creativity of the Tày and Nùng ethnic groups, combining Chinese influences with local mountain ingredients and flavors. It is a favorite dish in the hot summer months and often enjoyed at festive gatherings or as a light meal.

2. Key Ingredients & Characteristics

• Noodles (bánh phở):

  • Fresh, flat rice noodles are blanched and cooled, forming the base of the dish.

• Sour-sweet sauce:

  • A unique blend of tamarind juice or vinegar, sugar, fish sauce, and garlic, sometimes with soy sauce or chili.

  • The sauce is light yet flavorful, slightly thickened, and poured over the noodles.

• Toppings include:

  • Shredded chicken or pork belly

  • Roasted duck slices (optional in premium versions)

  • Fried shallots and crunchy peanuts
