Kobaizuke is an unusual Japanese plum confection made with thick-fleshed green plums grown in Ogi, a city neighboring Saga City to the west. Although it looks similar to traditional salted umeboshi pickled plums, it is actually a sweet preserve and is not sharply sour.
The plums used are the Shirokaga variety. Each plum is carefully prepared by removing its pit individually, then preserved using only sugar and generous quantities of shiso leaves, or Japanese perilla. This simple combination creates a distinctive sweet-and-sour taste and a refreshing aroma.
One of the most appealing features of Kobaizuke is its crisp texture. Unlike soft pickled plums, the fruit retains a satisfying crunch. Its flavor is gently sweet and sour, with a mild, rounded taste that spreads through the mouth, accompanied by the fresh fragrance of shiso.
Because the pits have been removed, the plums are easy to eat. Their appearance may resemble umeboshi, but their sweetness and crispness make them a very different kind of plum treat.
Kobaizuke is delicious served as an accompaniment to Japanese tea and makes a pleasant snack for children as well as adults.
It can also be finely chopped and added to barazushi, a colorful style of scattered sushi, where it provides a subtle sweet-and-sour accent that enhances the overall flavor.
The syrup left in the container is another treat in its own right. Rich in plum extract, it can be mixed with shochu, a Japanese distilled spirit, or diluted with soda water to make a refreshing drink.
With its carefully prepared seedless plums, fragrant shiso leaves, crisp bite, and versatile syrup, Kobaizuke is a distinctive local specialty from Saga that offers a fresh interpretation of traditional Japanese plum preserves.
