Thai spur chilies (Prik chee fah)

Prik chee fah also known as Thai spur chilies are popular type of chili pepper used in Thai cuisine.

They are larger and less spicy than the better known prik kee noo. The Thai spur chilies are typically about 10 to 13 cm (4-5 inches) long, with a conical shape, and mature from green to a bright red color. The flavor of these chilies is relatively mild and slightly sweet, making them more comparable to the Jalapeño or Serrano peppers in terms of heat.

Their Scoville Heat Units (SHU) typically range between 5,000 and 30,000. These chilies are often used in stir-fries, soups, and salads, and can be eaten raw, cooked, or pickled.
