Yong Chi, owner of the Center City Korean cafes Giwa and Rice & Mix, is bottling the hot sauce used at Giwa.
Under the name Yong's Kitchen, he is taking to market his version of go chu jang, the traditional paste made mainly with fermented soybean and red chili pepper.
Chi's sauce is at once spicy and sweet. He has it made by a food company in Lancaster County and says it's the same recipe used in the restaurant, except that the bottled version includes apple cider vinegar as a natural preservative.
It retails at the cafe for $5.95.
