What is "khao soi"?

Khao Soi is a popular Northern Thai dish that consists of a rich and fragrant curry soup made from a mixture of coconut milk, red curry paste, and a variety of spices such as coriander, turmeric, and cumin. The soup is usually served with egg noodles and a protein such as chicken or beef, and is often garnished with crispy fried noodles, shallots, and fresh cilantro. Khao Soi has a unique and complex flavor, with a creamy and slightly sweet taste that is balanced by a hint of spiciness. It is a popular street food in Northern Thailand and is also served in many Thai restaurants around the world.
