This is a bold, spicy seafood stir-fry sauce made by Sempio, one of Korea's most established food brands. Mukyo-dong is a famous street in central Seoul known for its squid and octopus stir-fry restaurants, and this sauce recreates that iconic flavour. It is very easy to use: stir-fry fresh seafood such as squid, small octopus, or cuttlefish with onion, spring onion, and carrot in a hot pan, pour in the sauce, and cook over high heat until everything is coated and fragrant. No additional seasoning is needed — one 130g pouch is the right amount for two servings.

This sauce contains multiple chilli-derived ingredients — Red Pepper Paste (Gochujang), Red Pepper Powder, Red Pepper Extract, and Oleoresin Capsicum — placing it in the medium-to-hot range by Korean standards, which may be quite spicy for those accustomed to European heat levels. If you are sensitive to spice, we recommend increasing the amount of seafood or using only half the pouch and refrigerating the rest. The combination of soy sauce, garlic, and fermented soy ingredients means the heat is balanced by a deep, complex umami flavour rather than being one-dimensional.

This sauce contains ingredients made through traditional fermentation methods, including Soy Sauce and Fermented Soy Peptide. These fermented components contribute a deep umami richness and layered flavour to the sauce. Just as European cheese and wine develop complexity through ageing, Korean soy sauce and Doenjang (fermented soybean paste) undergo months or even years of natural fermentation (naturally fermented) to achieve their distinctive depth. This is at the heart of a Korean food culture spanning thousands of years. Note that this product itself is a finished cooking sauce; the product as a whole is not a fermented food, but it is built on fermented ingredients.
