Despite what is commonly believed, there is no single “Thai pepper” though most peppers referred to as Thai are small in size and high in heat or pungency. There are at least 79 separate varieties of the pepper that have appeared from three species in Thailand.
As with many other types of chili peppers, there is strong debate about these peppers, and a particular confusion when it comes to Thai peppers.
Prik num or “banana peppers,” for example, resemble a New Mexican pepper, and they are also grown in Kashmir, India, and thus are also known as Kashmir peppers. It is further confusing as the Kashmir is ALSO known as the Sriracha, a name associated with the famous sauce originally made from these peppers in the Thai seaside town of the same name.
