Which Thai province gives its name to sen chan noodles in Pad Thai?

Chanthaburi Province gives its name to the sen chan noodles used in pad thai.

Sen chan means “Chan noodles,” referring to rice noodles associated with Chanthaburi in eastern Thailand. Pad thai made with these noodles is often called sen chan pad thai. The name distinguishes the noodle style from other Thai rice-noodle varieties and ties the dish to a specific regional source.

Chanthaburi has long been associated with rice-noodle production and distinctive noodle dishes. In the standard account of pad thai’s development, sen chan noodles became the noodle base for a nationally recognizable version of the stir-fried dish during the mid-20th century. The noodles are made from rice and are valued for their texture after soaking and wok-frying.

This answer is easy to confuse with Chonburi or Nonthaburi because all three are Thai provincial names ending in “-buri,” a common element meaning city or town. Sukhothai is also linked to a well-known noodle preparation, kuaitiao Sukhothai, but it is not the province named by sen chan. Chanthaburi is the specific place behind the noodle name.
