Ingredients: Onion kimchi is primarily made with onions as the main ingredient. Alongside onions, it typically includes garlic, ginger, green onions, and sometimes carrots or radishes. The seasoning often includes Korean red pepper flakes (gochugaru), fish sauce (or salted shrimp), sugar, and salt.
Preparation: Onions are usually cut into wedges or thinly sliced and then salted to draw out moisture. The seasoning mixture, which can vary slightly depending on the recipe, is then mixed with the onions. This mixture is thoroughly combined to ensure all the onions are coated with the flavorful seasoning.
Fermentation: Like traditional kimchi, onion kimchi undergoes a fermentation process. The salt and seasonings work to preserve the onions and encourage fermentation. Fermentation can take a few days to develop the desired tangy flavor. During fermentation, flavors deepen and develop complexity.
