YujacheongYuja citron preserve
When the first frost comes to Goheung in South Jeolla and Namhae island in November, the yuja orchards turn gold, and households slice the knobbly, deeply perfumed fruit into sugar to make yujacheong. Through the winter, a few spoonfuls in a mug of hot water make yuja-cha, the tea Koreans reach for on cold evenings and when they feel a cold coming on; it is also spooned over yoghurt, toast or into salad dressings. It tastes floral, sharp and sweet, with tender strips of peel and a thick golden syrup. The sugar is what preserves it: equal weights of fruit and sugar, kept in the fridge once the sugar dissolves. The common mistake is leaving it warm too long: after a day or two on the counter it can start to ferment and fizz, so move it to the fridge as soon as the sugar has mostly melted. It is ready after about a week, when the peel is translucent and the syrup thick. No yuja? Use Meyer lemons, or two lemons for every mandarin. Bubbles or a boozy smell mean it has started to ferment: refrigerate it at once; mould means throw it away. Chef's tip: scrub the skins with baking soda first; you are eating the whole peel, so it must be spotless.
