Gochujang's unique flavor comes from fermented red chili powder (gochugaru), glutinous rice, fermented soybeans (meju powder), and salt. These ingredients, combined with the fermentation process, create its complex sweet, savory, and spicy profile.
Gochujang's distinctive taste is a result of a carefully balanced combination of ingredients and a lengthy fermentation process. Here's a breakdown of the key components:
Gochugaru (Korean Chili Powder): This is the foundation of Gochujang's spiciness and vibrant red color. The type and quality of gochugaru significantly impact the final flavor. It's not just about heat; gochugaru also contributes a subtle fruity and smoky note.
Glutinous Rice (Sweet Rice): Glutinous rice provides the starch necessary for fermentation and contributes to the paste's sweetness and thick texture. The rice is often cooked and then mixed with the other ingredients.
Meju Powder (Fermented Soybean Powder): Meju is a block of dried fermented soybeans. It's ground into a powder and adds a deep umami flavor to Gochujang. The fermentation process breaks down the proteins in the soybeans, creating complex amino acids that contribute to the savory taste.
Salt: Salt acts as a preservative and controls the fermentation process. It also enhances the other flavors and contributes to the overall balance of the paste.
Optional Ingredients: Some recipes may include other ingredients like barley malt powder (yeotgireum), which adds sweetness and aids in fermentation, or alcohol to further control the fermentation process and add complexity.
The fermentation process, which can last for months or even years, is crucial. During this time, enzymes break down the starches and proteins, creating a complex array of flavors that define Gochujang.
When buying Gochujang, look for products that list 'Korean chili powder' or 'gochugaru' as the primary ingredient. Avoid those with excessive additives or artificial flavors, as they may compromise the authentic taste.
