Korean Chili Varieties: A Comprehensive Guide
In Korean cuisine, chilli peppers (gochu) come in distinct varieties that each serve specific culinary purposes. The basic classification distinguishes between put-gochu (풋고추), young green chilies prized for their fresh flavour, and hong-gochu (홍고추), the mature red chilies that develop a deeper, complex taste. The term cheong-gochu (청고추) encompasses various green chilli varieties.
The Cheongyang chilli (청양고추), a hybrid between Jeju Island's local variety and Thai chillies, delivers significant heat at 10,000 Scoville Heat Units (SHU). Whether used fresh in stir-fries or dried into gochugaru, it's essential in dishes like gochujang eomuk bokkeum. Meanwhile, the wrinkled, compact kkwari-gochu (꽈리고추), also known as Shishito, offers a milder heat at 1,000 SHU and features prominently in dishes like myulchi bokkeum and jangjorim.
Most varieties flourish as summer crops, with different regions producing distinct flavour profiles due to variations in soil and climate. This diversity of chillies, developed through centuries of selective breeding, forms the backbone of Korean cuisine's distinctive spice profile, demonstrating the sophistication of Korean culinary traditions and their deep understanding of how different chilies contribute to a dish's character.
The preservation and cultivation of these distinct chilli varieties remains a point of pride in Korean agriculture, with many regions hosting annual festivals celebrating their local varieties. These events not only showcase traditional farming methods but also highlight the crucial role these peppers play in Korean food culture, from home kitchens to industrial production. Farmers often pass down specialized growing techniques through generations, maintaining the unique characteristics that make each variety distinct and irreplaceable in Korean cuisine.
