The History and Cultural Influence of Khao Soi

✔ Khao Soi originated from Northern Thailand, heavily influenced by Burmese and Chinese Muslim traders who introduced coconut milk-based curries and egg noodles to the region.
✔ The name “Khao Soi” translates to “cut rice,” referring to how noodles were traditionally hand-cut.
✔ Unlike central and southern Thai curries, Northern Thai cuisine tends to be milder, with a focus on earthy and warming flavors.

📌 Fun Fact: There are different versions of Khao Soi—Chiang Mai-style (Thai) and Shan-style (Burmese), with the Thai version being more coconut-heavy and the Burmese version spicier and brothier.

Key Ingredients for Authentic Khao Soi

1. Protein Choice (Chicken, Beef, or Tofu) 🍗🥩🌱

✔ Traditionally made with bone-in chicken thighs or drumsticks for maximum flavor.

2. The Curry Paste (The Soul of Khao Soi) 🌶️
