Cheongyang chili pepper (Cheongyang gochu)

The Cheongyang gochu or Cheongyang chili pepper is a popular and spicy variety of chili pepper commonly used in Korean cuisine. It's named after the Cheongyang region in South Korea, where it is widely cultivated. Cheongyang chili peppers are known for their higher heat level, around 10,000 Scoville heat units.

They are significantly spicier than regular Korean chili peppers (gochu), and their spiciness can be compared to that of a serrano pepper. This makes them suitable for those who enjoy a strong, spicy kick in their dishes. These peppers are usually green in color, though they can turn red when fully ripe.

They are long, slender, and slightly curved, resembling the common green chili peppers but with a more intense heat. Cheongyang chili peppers are used in various Korean dishes to add spiciness and flavor. They can be used fresh, sliced, or chopped in salads, stews, soups, and marinades.

They are also a popular ingredient in kimchi recipes for those who prefer a spicier version of this traditional Korean dish.
