For the end of this summer course, sweet and sour Kawachi-bankan jelly is refreshing. Kawachi Bankan is a large, yellow citrus that can be harvested from early-summer to summer. It looks and feels similar in size to grapefruits. However, unlike grapefruit, it lacks bitterness and has a sweetness to it that can be enjoyed refreshingly. This time, I chose a turquoise-blue colored tray that is reminiscent of summer, contrasting beautifully with the yellow color of the jelly. The combination of the opposite colors gives a summery look to the dish. Kawachi bankan can be substituted with grapefruit, orange, etc., so please try using your favorite citrus fruits. If you like alcohol, you can enjoy it by adding liqueur such as Cointreau.
