May 1, 2023

Gochugaru, the bright red spice that lends many Korean dishes their characteristic flavour and colour, is likely already familiar to anybody who enjoys Korean cuisine. Gochugaru is a sun-dried Korean chilli pepper powder that is coarsely powdered. Depending on the kind and brand, it may have a mild to moderate amount of heat with a flavour profile that blends spicy, sweet, and smokey elements.

Gochugaru is a staple ingredient in Korean cuisine, and is essential for preparing kimchi, the fermented vegetable dish revered as the country’s national dish. Gochujang, a thick and savoury chilli paste used as a condiment and a foundation for many sauces and marinades, relies on gochugaru as a key component. Soups, stews, noodles, rice cakes, dumplings, pancakes, and many more dishes benefit from gochugaru’s vibrant colour and spicy flavour.

Everything you need to know about gochugaru is covered here: its origins, cultivation, varieties, medicinal properties, culinary applications, and potential alternatives. We will also discuss where to get gochugaru, how to keep it fresh, and how to incorporate it into your own cooking.

The History of Gochugaru

In the late 16th century, Portuguese merchants brought chilli peppers from Japan to Korea. Chilli peppers originated in the Americas. Before then, most Korean food was bland and salty, seasoned with salted fish and soy sauce. Koreans immediately discovered the deliciousness, beauty, and health advantages of chilli peppers. Food was preserved because they stopped germs from multiplying.

The 1614 encyclopaedia Collected Essays of Jibong has the first known reference to chilli pepper in Korea. Around the year 1700, a book titled Farm Management discussed the growing techniques for chilli peppers. Chilli peppers were a popular crop and food item in Korea by the 18th century.

Gochugaru is a Korean spice blend whose name comes from the words for “chilli pepper” (gochu) and “powder” (garu). Gochugaru is made by dehydrating fresh chilli peppers in the sun or a dehydrator, then flaking or powdering them after removing the seeds and membranes. Historically, stone mills were used either at home or by local millers to produce gochugaru. The vast majority of gochugaru consumed today was manufactured in a factory, ground using an electric grinder, and sold in plastic containers.

The Production of Gochugaru

The kind of chilli peppers used and the drying procedure greatly affect gochugaru’s quality and flavour. The “sun-dried” chilli peppers known as taeyangcho () are the most popular choice for making gochugaru. Harvested while bright red in colour, these peppers are sun-dried for many days until they become wrinkled and brittle. The peppers’ original colour and fragrance are maintained throughout the sun-drying process, and they acquire a subtle smokiness as a result.

Green peppers, or cheongyangcho, are another kind of chilli pepper used in gochugaru. These peppers are picked when they are still immature and green, then dried using heat or infrared rays. The cheongyangcho pepper, often known as the red pepper, is smaller and hotter than its taeyangcho counterpart.

Before they are ground into flakes or powder, dried chilli peppers have their seeds and membranes removed. Removing the seeds from gochugaru makes it less spicy since that’s where most of the capsaicin, the substance responsible for chilli peppers‘ heat, is found. Gochugaru’s flavour might be impacted by the membranes’ harsh aftertaste. Next, the flakes or powder are sifted to get rid of any remaining dust or debris.

The Varieties of Gochugaru

Gochugaru can be classified into different varieties based on several factors, such as:

  • Texture: The texture of gochugaru may range from coarse to fine. The bigger flakes of coarse gochugaru give food a more robust appearance and flavour. Smaller granules of fine gochugaru disperse more evenly when cooked. The size of the grinder and sifter employed will determine the consistency of the resulting gochugaru.
  • Heat level: The heat level of gochugaru may vary widely. Gochugaru’s spiciness may be adjusted by using milder chilli peppers or by leaving some of the seeds and membranes in. Red peppers are often hotter than green peppers, while cheongyangcho peppers are typically hotter than taeyangcho peppers. Gochugaru packages often have a star or chilli symbol rating its spiciness.
  • Origin: Gochugaru may be made using either locally sourced or imported ingredients. Peppers from other nations, including China, India, or Spain, are used to make imported gochugaru instead of the domestic Korean kind. The original flavour and higher quality of domestic gochugaru is why Koreans are willing to pay a premium for it. Although imported gochugaru is more accessible and often less expensive, it may have a different flavour profile or added ingredients.

Some examples of gochugaru varieties are:

  • Gochugaru for kimchi: This gochugaru is gritty and somewhat spicy; it was developed specifically for use in preparing kimchi. Its rich flavour and vibrant red colour make it a great addition to kimchi.
  • Gochugaru for soup: This gochugaru is a high-quality, mildly spicy type developed specifically for use in stews and soups. Its vibrant crimson colour and crisp taste provide stews and soups a welcome spiciness.
  • Gochugaru for seasoning: Designed specifically for use as a seasoning, this kind of gochugaru packs a serious punch. Its bright red colour and sharp taste make it an excellent choice for recipes that need a kick.

Capsaicin works by stimulating these receptors in the brain, making them less sensitive to pain. Headaches, muscular pains, menstrual cramps, and neuropathy are just some of the ailments that might benefit from this impact.
  • It enhances mood. Gochugaru also causes the brain to produce more feel-good endorphins.
