Bird's eye chilies (Prik kee noo)

Prik kee nu or bird's eye chilies are small, spicy chili peppers that are very popular in Thai and other Southeast Asian cuisines.

They're also commonly referred to as Thai chilies as they are the most popular variety, but they are in fact just one of many Thai chili cultivars. These chilies have a vibrant flavor and are quite hot, typically much more so than jalapeños or serrano peppers.

The Scoville Heat Units (SHU) for Prik kee nu chilies can range from 50,000 to 100,000, making them significantly hotter than jalapeños (2,500-8,000 SHU) but less so than habaneros (100,000-350,000 SHU). In cooking, they're often used in stir-fries, curries, salads, and sauces to add a spicy kick.
