Yuja-Cheong — Korean Yuzu Citrus Preserve (유자청)

Origin

Yuja (Citrus junos) is grown along the southern coast of Korea, and its cultivation there is traced to the Goryeo period. Yuja-cheong belongs to the Korean tradition of preserving fruit in sugar, the cheong method that also yields maesil-cheong from green plums, and it is made today in the coastal households of South Jeolla and South Gyeongsang, where the fruit ripens in late autumn.

Description

Yuja-cheong (유자청) is the Korean preserve of yuja (유자, Citrus junos, Korean yuzu) — sliced whole yuzu including peel and seeds combined with equal weight of sugar and left to ferment and macerate at room temperature for 3 months or longer. The result is a thick, fragrant syrup with suspended yuzu peel slices that functions as a tea base (유자차, yuja-cha, made by dissolving a spoonful in hot water), a sauce for desserts, a marinade brightener, and a condiment for duck and seafood dishes. Korean yuja, grown primarily in Goheung county (고흥군, South Jeolla), has a more aromatic skin and more acidic juice than Japanese yuzu.

The Thread

—Both preserve the aromatic oils of citrus peel in sugar, so that the fragrance of the fruit outlasts its season. Marmalade is boiled to a set with pectin, while yuja-cheong is left raw to macerate and ferment, which keeps the peel supple and the syrup loose. British

—Both capture the perfumed skin of yuzu in a preserving medium, which is the part of the fruit that carries its character. Yuzu kosho uses salt and chilli to make a pungent seasoning paste, whereas yuja-cheong uses sugar to make a sweet syrup for tea and sauces. Japanese

—Both draw the aromatic compounds from citrus peel into a sweetened liquid that is kept for months and diluted or measured out in small amounts. Limoncello extracts them in alcohol and is drunk as a digestif, while yuja-cheong extracts them in sugar and its syrup serves as a tea base and a seasoning. Italian

Flavour Context

Yuja-cheong's function in Korean cooking is brightening and fragrance addition — a small amount added to seafood marinades, duck braises, or dessert sauces provides the citrus lift that makes a dish smell and taste complete. Unlike lemon, yuzu's aromatic profile is floral and complex; yuja-cheong carries this character into any dish it enters.
